Lock the state directory and write vault files atomically (closes #34)

Each command that changes the state directory holds one lock: flock(2)
on `lock` in the state directory, dropped by the kernel if the process
dies, or a process-wide mutex on the in-memory test filesystem. It
covers the state directory, not each vault, because `currentvault`,
`vault create` and cross-vault moves span vaults, and a lock file in a
vault would be deleted by `vault remove` under a waiting command.
Serializing changes across vaults costs a command-line tool nothing.

Files go through `secret.WriteFileAtomic`; versions, new secrets and
cross-vault copies are built in a temporary directory and renamed into
place; removals rename out of the way first.

 # Completed Steps
 
-- 2026-10-04: `secret unlocker add pgp` works on Linux
-  (https://git.eeqj.de/sneak/secret/issues/88). `CreatePGPUnlocker` gets
-  the vault's long-term key as adding a passphrase unlocker does, with the
-  vault's `GetOrDeriveLongTermKey`, now part of `VaultInterface`: from the
-  mnemonic, checked against the vault, or else from the current unlocker.
-  Before, it used the keychain unlocker's helper, which on every platform
-  but macOS always failed. A test adds a PGP unlocker for a throwaway GPG
-  key, getting the long-term key once from the mnemonic and once from a
-  passphrase unlocker, and reads a secret through the new unlocker.
-- 2026-10-04: A vault name may use only lowercase ASCII letters, digits,
-  `.`, `-` and `_`, and must not be empty, `.` or `..`
-  (https://git.eeqj.de/sneak/secret/issues/68); the error and `README.md`
-  state the rule. `vault create`, `vault import`, `vault select`,
-  `vault remove`, both vault names of `mv` and shell completion of a
-  `vault:secret` argument check the name as typed with
-  `vault.ValidateVaultName` before building any path from it. Before,
-  `vault import ..` wrote a long-term key and an unlocker into the state
-  directory itself, and `vault select ..` made that the current vault.
-- 2026-10-04: `script/cibuild` runs the checks again on an unchanged
-  tree (https://git.eeqj.de/sneak/secret/issues/54). It passes the
-  current time as the `CHECK_EPOCH` build argument, which both the lint
-  and the build stage of the `Dockerfile` declare after their module
-  download, so the `RUN` steps below the argument run again on each
-  build while the base images and module downloads stay cached. Before,
-  a second run on the same tree took every check from the build cache
-  and reported success having run nothing.
-- 2026-10-04: A failed unlocker add no longer leaves a partial unlocker
-  directory (https://git.eeqj.de/sneak/secret/issues/48).
-  `secret unlocker add pgp` resolves the GPG key's fingerprint once, for
-  its duplicate check, and passes it to `CreatePGPUnlocker` to record.
-  `CreatePGPUnlocker` and `CreateKeychainUnlocker` get the long-term key
-  and encrypt everything before writing anything. All four unlocker
-  types write their files through `secret.WriteDir`: a new unlocker is
-  built in a temporary directory, renamed into place when complete and
-  removed on a failure. One added under the directory name of an
-  existing unlocker is still written into that directory in place
-  (https://git.eeqj.de/sneak/secret/issues/71).
-- 2026-10-04: `secret unlocker select` and `secret unlocker remove`
-  skip, with the warning `unlocker list` gives, an unlocker directory
-  whose metadata file cannot be checked for, read or parsed, instead of
-  failing when it sorts before the unlocker asked for. Such a directory,
-  or one without a metadata file, is removed by its directory name, the
-  name the warning gives; only the directory is removed, since its type
-  is unknown. Removing one whose metadata file is missing or corrupt
-  never counts as removing the last unlocker. Removing one whose metadata
-  file cannot be checked for or read always does, since it may be the
-  only working unlocker, so in a vault with secrets it needs `--force`.
-- 2026-10-04: A failed command prints its error once, without the usage
-  text after it (https://git.eeqj.de/sneak/secret/issues/41). Usage is
-  still printed for a command called wrongly: wrong number of arguments,
-  unknown flag, bad flag value, missing required flag, or flags that
-  break a flag group (mutually exclusive, required together, one
-  required). The root command's `PersistentPreRunE` turns usage off.
-  Cobra checks arguments and flag values before that hook but required
-  flags and flag groups only after it, so the hook checks those two
-  first. Root `SilenceUsage` would have hidden usage for all of these.
-- 2026-10-04: `secret get` keeps the secret in locked memory until it
-  writes it out (https://git.eeqj.de/sneak/secret/issues/37):
-  `Vault.GetSecret` and `Vault.GetSecretVersion` return a
-  `*memguard.LockedBuffer`, which every caller destroys, and `secret get`
-  writes its bytes straight to stdout, still with no trailing newline.
-  Before, the value was copied into ordinary memory that nothing wiped,
-  and `get --version` also wrote it to the debug log.
-- 2026-10-04: The `Makefile` no longer sets `DOCKER_HOST`, so its docker
-  targets use the local docker daemon, or whatever `DOCKER_HOST` the
-  environment sets. `make build` calls the new `script/build`, which
-  stamps the version (`VERSION` from the environment, else
-  `git describe`) and the git commit as before. `build`, `clean`,
-  `install` and `docker-run` are in `.PHONY`; `make install` depends on
-  `build`. The `vet` target is gone: `script/test` runs `go vet` first.
-- 2026-10-04: `.gitignore` is the org's standard file, which ignores
-  `.env`, `.env.*`, `*.pem` and `*.key` and editor and OS files, plus
-  this repo's `/secret`, `*.log`, `*.test` and `settings.local.json`
-  (https://git.eeqj.de/sneak/secret/issues/40). `.dockerignore` also
-  leaves out `node_modules`; `.git` stays in the build context for the
-  version stamp.
-- 2026-10-04: `secret init` refuses when the default vault exists, and
-  `secret vault create NAME` when `NAME` does, with "vault NAME already
-  exists", before writing anything. The check is in `vault.CreateVault`,
-  which both commands call while holding the state directory lock, so two
-  creates of one vault at once cannot both pass the check. Before, either
-  command replaced the vault's metadata, passphrase unlocker and
-  `longterm.age`, so none of its secrets could be decrypted any more. Both
-  commands now ask for the unlocker passphrase before creating the vault,
-  so one stopped at that prompt leaves no vault behind.
-- 2026-10-04: The `internal/cli` tests are back to about their time
-  before the state directory lock
-  (https://git.eeqj.de/sneak/secret/issues/80). The test that each
-  changing command waits for the lock releases it as soon as it sees the
-  command waiting there, instead of after a fixed 100 ms. The two vaults
-  with passphrase unlockers that the path and move tests start from are
-  made once and copied for each test.
-- 2026-10-04: `secret mv` rejects a move whose destination is the source
-  under another name, such as `foo` for `Foo` on a case-insensitive
-  filesystem (the macOS default) or a name reached through a symbolic
-  link, before changing anything, with or without `--force`, within a
-  vault and between vaults; before, `--force` removed the destination and
-  so deleted the secret. A rename that changes only letter case works on a
-  case-sensitive filesystem as before.
-- 2026-10-04: Lint runs only in docker: `script/lint` builds
-  `Dockerfile.lint`, where golangci-lint is a build step rebuilt on
-  every run (`--no-cache-filter`), so an unchanged tree is linted too;
-  the module download stays cached. `script/bootstrap` no longer
-  installs golangci-lint, and the `Dockerfile` lint stage calls it
-  directly instead of `make lint`. `golangci-lint config verify` is not
-  run: it fetches its schema live over unpinned HTTPS.
-- 2026-10-04: A PGP unlocker whose metadata has no usable GPG key ID
-  no longer panics: `GetID()` warns with the unlocker's directory and
-  returns `pgp-unknown`. `ListUnlockers` skips, with a warning, an
-  unlocker whose metadata file cannot be checked for, read or parsed
-  instead of failing, so `secret unlocker list` still lists the others;
-  the listing's ID lookup no longer warns about that directory again.
-- 2026-10-03: `secret mv` rejects a move whose destination is the
-  source (`mv --force x x`, `mv --force work:x work:`, or an empty
-  destination, which defaults to the source name) before changing
-  anything; before, `--force` removed the destination first and so
-  deleted the secret. Every vault name given with `vault:` must be one
-  of the existing vaults by exact name, so `work:x work/:x` is rejected
-  instead of being taken for a move between two vaults. A move within a
-  named vault no longer makes that vault the current one, whether it
-  succeeds or fails.
 - 2026-10-03: Commands that change the state directory hold one lock
   (`flock` on `lock` in the state directory; a mutex on the in-memory
   test filesystem), so concurrent commands no longer lose versions or
   race on the current pointers. Every file is written through
-  `secret.WriteFileAtomic` (temporary file, sync, rename), so no file
+  `secret.WriteFileAtomic` (temporary file, sync, rename); new
-  is ever half-written and `current`, `currentvault` and
+  versions, new secrets and cross-vault copies are built in a
-  `current-unlocker` never go missing. New versions, new secrets and
+  temporary directory and renamed into place, and removals rename out
-  cross-vault copies are built in a temporary directory and renamed
+  of the way first, so an interrupted command leaves nothing
-  into place, and removals rename out of the way first, so a version
+  half-written.
-  or secret is never half-added and never half-removed. An
-  interrupted command can still leave:
-    - a broken unlocker, when it was replacing one: an unlocker added
-      under the directory name of an existing one is rewritten file by
-      file. That happens to a passphrase unlocker added to a vault that
-      has one, and to a PGP, keychain or Secure Enclave unlocker added
-      on the same host and day as another of its type
-      (https://git.eeqj.de/sneak/secret/issues/71);
-    - from `init` or `vault create` killed after the passphrase prompt
-      but before the unlocker is written, a vault with no unlocker,
-      which `vault create` has already made the current vault;
-    - data under a `.tmp-` name in the state directory: a secret,
-      version or unlocker being added, or the secret, version, unlocker
-      or vault being removed, encrypted keys included. Nothing deletes
-      it; it must be deleted by hand
-      (https://git.eeqj.de/sneak/secret/issues/75).
-- 2026-10-03: The checks run before changing a vault now stop with an
-  error naming the path and cause when they cannot read what they
-  inspect, instead of reading the failure as "nothing there": the
-  duplicate check before `unlocker add pgp` (an unreadable
-  `unlockers.d` or unlocker metadata file), the secret count that
-  guards removing the last unlocker and removing a vault, and the
-  existing long-term key check before `vault import`.
-- 2026-10-03: `version rm`, `version promote` and `get --version`
-  accept a version only if it is one of the versions `version list`
-  lists for that secret, compared as typed before any path is built
-  (`secret.VersionExists`), and touch nothing otherwise. An empty
-  `--version` is rejected instead of meaning the current version.
-  Before, `secret version rm x ../../..` deleted the whole vault,
-  `secret version rm x ..` the secret, and `.` or `""` every version.
-- 2026-10-03: Key material is wiped on every exit: `Entry()` returns
-  the exit code after its deferred `memguard.Purge()` has run, and only
-  `main` calls `os.Exit`. SIGINT and SIGTERM go through memguard's
-  handler, which wipes every buffer before exiting; when the process is
-  in the terminal's foreground process group it first restores the
-  terminal settings from startup, so an interrupted passphrase prompt no
-  longer leaves echo off.
-- 2026-10-03: Every command that builds a path from a secret name
-  checks the name first with `vault.ValidateSecretName` and touches
-  nothing when it is invalid: `rm`, `mv` (both names, within a vault
-  and between vaults, before switching the current vault), `import`,
-  `version list`/`promote`/`rm`, `encrypt` and `decrypt`. The error
-  and `README.md` state the naming rule. Before, `secret rm ..`
-  deleted the whole vault and `secret rm .` every secret in it.
-- 2026-10-03: The keychain unlocker's age key passphrase stays in
-  locked memory: it is generated into a locked buffer, and the
-  keychain JSON is written and read by `KeychainData` code in
-  `internal/secret/keychaindata.go` (tested on Linux) without
-  `encoding/json` holding it; the JSON field names are unchanged.
