Delete the keychain item or Secure Enclave key of a failed unlocker add (closes #89 )

A Secure Enclave unlocker add gets the long-term key before it creates the Secure Enclave key, so a wrong passphrase creates none, and deletes the key if a later step fails. macse.CreateKey finds the new key's hash right after sc_auth creates it, failing with an error naming the label if it cannot, and deletes the key if getting its public key then fails. A keychain unlocker add writes all of the unlocker's files before it stores the keychain item, and deletes the item if moving the unlocker into place then fails. A failure to delete is reported along with the original error. The Objective-C and macse_darwin.go were only read, never compiled or run; the new tests run only on a Mac. Model: opus-5-5

 # Completed Steps
 - 2026-10-05: The Go module path is `sneak.berlin/go/secret`, as
  `REPO_POLICIES.md` requires, not `git.eeqj.de/sneak/secret`
  (https://git.eeqj.de/sneak/secret/issues/43). Every import uses it, as do the
  `-X` flags in `script/build` that stamp the version and commit shown by
  `secret info`, and the examples in `pkg/agehd/README.md` and
  `pkg/bip85/README.md`. `go mod tidy` now lists `github.com/dustin/go-humanize`
  and `github.com/fatih/color`, which `internal/cli` imports, as direct
  requirements. Code that imported the old path must switch to the new one.
 - 2026-10-04: `make fmt` formats every markdown file with prettier (4-space
  tabs, `proseWrap: always`) as well as the Go code, and `make fmt-check` checks
  both, as the model scripts in the `prompts` repo do
  (https://git.eeqj.de/sneak/secret/issues/110). Prettier is pinned by hash in
  `package.json` and `yarn.lock`, and `script/bootstrap` installs node, yarn and
  prettier. The `Dockerfile` lint stage copies node and yarn from a node image
  pinned by hash and runs `script/bootstrap`, so its `make fmt-check` fails the
  build on an unformatted markdown file. Every markdown file was formatted once,
  wording unchanged.
 - 2026-10-04: A mnemonic that cannot be read, in `secret init` and
  `secret vault create`, gives an error that names the mnemonic only
  (https://git.eeqj.de/sneak/secret/issues/115). It is read with
  `secret.ReadMnemonic`, whose every error wraps the new
  `secret.ErrMnemonicNotRead`; before, it was read with `ReadPassphrase`, so the
  message said "failed to read mnemonic: failed to read passphrase:" and advised
  setting `SB_UNLOCK_PASSPHRASE`. Without a terminal it now says "failed to read
  mnemonic: stdin is not a terminal (piped input or script). Please set the
  SB_SECRET_MNEMONIC environment variable or run interactively". The passphrase
  messages no longer repeat "cannot read passphrase" after "failed to read
  passphrase:", and empty input gives "nothing was entered".
 - 2026-10-04: A failure returns the same error value whichever command hits it
  (https://git.eeqj.de/sneak/secret/issues/113). `internal/cli` no longer keeps
  its own copies of `vault.ErrSecretNotFound`, `ErrVaultNotFound`,
  `ErrVersionNotFound` and `ErrSecretExists`: `secret mv`, `rm`, `decrypt`,
  `vault import`, `vault remove` and `version list`, `promote` and `rm` wrap the
  `vault` errors. `errUnsupportedUnlockerType` is removed: `secret unlocker add`
  gives `errInvalidUnlockerType` for an unknown type, whichever check rejects
  it. Off macOS, adding a keychain or Secure Enclave unlocker returns the
  `secret` package's error for it, not an `internal/cli` copy; on macOS, the
  check that the system is macOS is gone, as it could never fail.
  `secret vault import` gives `errInvalidMnemonicPhrase` for an invalid
  mnemonic, as `init` and `vault create` do. `secret generate secret` gives
  `errLengthTooSmall` for a length below 1 wherever it is checked, and
  `errUnsupportedSecretType` for `--type mnemonic` too. `secret import` of a
  file over 100MB wraps `errSecretTooLarge`, as `secret add` returns it.
  `vault.ErrNilValueBuffer` is replaced by `secret.ErrNilValueBuffer`, which
  `secret` already returned under another name. Messages are unchanged, except
  that `secret decrypt` of a missing secret says "not found", as `secret get`
  does, not "does not exist"; `vault import` of an invalid mnemonic says
  "invalid BIP39 mnemonic phrase"; `--type mnemonic` says "unsupported type:
  mnemonic (use 'secret generate mnemonic' instead)"; and a file too large to
  import says
  `failed to read secret from file <path>: secret too large: exceeds 100MB limit`.
  Every error of `secret.ReadPassphrase` wraps `secret.ErrPassphraseNotRead`,
  which supplies the words "failed to read passphrase" that its callers used to
  add themselves; so two passphrases that differ now give only "passphrases do
  not match", the words now follow "failed to read mnemonic:" and "failed to
  read passphrase confirmation:", and a terminal read error no longer repeats
  them. A GPG key the keyring does not hold gives `secret.ErrGPGKeyNotFound`,
  found by gpg's status line for "No public key"; before, the message repeated
  "failed to resolve GPG key fingerprint" and ended in gpg's exit status. The
  keychain unlocker returns `errNilDataBuffer` for nil data; this and its test
  build only on macOS with cgo and were only read. `bip85.ErrPasswordTooShort`
  and `ErrEncodedTooShort` are removed with their checks: 64 bytes of entropy
  always give 86 Base64 or 80 Base85 characters, the most a password length may
  ask for. Tests that matched these errors' text use `errors.Is`.
 - 2026-10-04: Tests check which error a failure returns with `errors.Is`, not by
  matching words of its message (https://git.eeqj.de/sneak/secret/issues/49).
  Every exported error that can be returned has a test that the function returns
  it, and errors wrapping a cause are checked through the wrapping. Checks that
  still match text, because the error has no exported value the test can name,
  are listed on the issue.
 - 2026-10-04: When a vault cannot be opened through its current unlocker,
  because a file the unlocker needs is missing or damaged, its keychain item or
  Secure Enclave key is gone, or the passphrase is wrong, the error now ends by
  naming the vault, saying that it still opens with its mnemonic, and that
  `secret unlocker add passphrase`, run with `SB_SECRET_MNEMONIC` set to it,
  gives the vault a new unlocker; for a vault that is not the current one, as in
  `secret move` between vaults, it says to run `secret vault select` first
  (https://git.eeqj.de/sneak/secret/issues/47). Before, it ended with the bare
  cause. The advice is given only when the vault metadata records the key the
  mnemonic derives, so not for a vault created without a mnemonic, and not when
  the passphrase could not be read at all. `secret vault import` is not named:
  it refuses a vault that has a long-term key. `secret encrypt` and
  `secret decrypt` now read the key secret through `vault.GetSecret`, as
  `secret get` does, so they give the same advice; `Secret.GetValue`, the other
  way to get the long-term key, is removed. When a secret's `current` file
  cannot be read, the error says that `secret version list` lists its versions
  and `secret version promote` makes one current. The causes stay wrapped.
 - 2026-10-04: An unlocker's ID is the name of its directory in `unlockers.d`, so
  no two unlockers of a vault share one
  (https://git.eeqj.de/sneak/secret/issues/98). Before, a keychain or Secure
  Enclave unlocker's ID was its creation time to the minute and the host name,
  and a passphrase unlocker's the time to the minute, so two created within a
  minute shared an ID, and `unlocker select`, `unlocker remove` and the
  selection `unlocker add` makes acted on the older one. A PGP unlocker's ID was
  `pgp-` and its key's fingerprint; a second PGP unlocker for a key is still
  refused, now by comparing the fingerprint in the other unlockers' metadata.
  `unlocker list` and the shell completion of `unlocker select` and
  `unlocker remove` take each ID from the directory the unlocker was read from,
  no longer by matching metadata, so two unlockers with the same metadata are
  listed apart; an unlocker of an unknown type is listed under its directory
  name, and completion now offers Secure Enclave unlockers too. The keychain and
  Secure Enclave code was type-checked by `script/lint-darwin`, never run; a
  test on Linux lists, completes, selects and removes each of two passphrase
  unlockers with the same metadata by its own ID.

  Details and Testing text matches the code

  are plain files holding a name, not symbolic links; a version's metadata is
  the encrypted `metadata.age`; the state directory is `berlin.sneak.pkg.secret`
  in the user's configuration directory, not `~/.local/share/secret`, and holds
  the `lock` file. Also corrected: the code sets up no Touch ID for the keychain
  or Secure Enclave unlocker, and the Secure Enclave only decrypts; per-version
  keys give no forward secrecy; `pub.age` is not age-encrypted; vault metadata
  holds no vault name. Testing lists only `make test`.
 - 2026-10-04: `secret init` and `secret vault create` create a vault whole or
  not at all (https://git.eeqj.de/sneak/secret/issues/105). `vault.CreateVault`
  now takes the unlocker passphrase too, writes the vault directory with its
  metadata, long-term public key and passphrase unlocker, `longterm.age`
  included, into a temporary directory, renames that into `vaults.d` once it is
  complete, and only then makes the vault current. Before, either command killed
  after the passphrase prompt but before the unlocker was written left a vault
  with no unlocker, which `vault create` had already made current and which
  neither command would create again. Killed part-way now, it leaves no vault,
  and the next command that takes the lock deletes the temporary directory; or,
  killed between the rename and making the vault current, a complete vault that
  is not current, which `secret vault select` makes current.
