Remove secret vault import (closes #139)

`secret vault import` took only a vault without a long-term key, and
`secret init` and `secret vault create` give every vault one, so it
always failed. A mnemonic enters through those two commands, so the
command goes, with its tests and its README entry. The help and the
note of `secret generate mnemonic` named `secret import`, which imports
a file as a secret; they now name `secret init` and
`secret vault create`.

`secret vault import` now prints the help of `secret vault` and exits
0, as cobra does for any subcommand of `secret vault` it does not know.

Judgement call: TestWorkflowMismatch in internal/vault, which replayed
the import step by step, is deleted.

Model: opus-5-5

 # Completed Steps
 
+- 2026-10-14: A wrong passphrase, from `SB_UNLOCK_PASSPHRASE` or typed at the
+  prompt, gives the error `wrong passphrase for unlocker <id>`
+  (https://git.eeqj.de/sneak/secret/issues/157). It used to be age's "no
+  identity matched any of the recipients", followed by advice to give the vault
+  a new unlocker from its mnemonic, which would have replaced an unlocker that
+  works. The error now wraps `secret.ErrWrongPassphrase` and carries no advice
+  to use the mnemonic. A `priv.age` that is not an age file still gets that
+  advice.
+- 2026-10-14: The passphrase and mnemonic prompts ask on the controlling
+  terminal (`/dev/tty`) instead of stdin, so `echo v | secret add s1 --force`,
+  `cat file | secret encrypt key` and `cat file.age | secret decrypt key` ask
+  for the passphrase at a terminal instead of failing
+  (https://git.eeqj.de/sneak/secret/issues/144). Only a process with no
+  controlling terminal gets the error that names the variable to set. On SIGINT
+  or SIGTERM, `Entry()` restores the settings of that terminal, not of stdin,
+  since that is where the prompt turns echo off. `secret init` and
+  `secret vault create` no longer write a newline to stderr after the mnemonic
+  is typed, since the prompt ends that line on the terminal.
+- 2026-10-14: `secret generate mnemonic`, `secret vault list` and
+  `secret unlocker list` print their output to stdout, as `secret list` does, so
+  it can be piped or captured (https://git.eeqj.de/sneak/secret/issues/138).
+  They printed with cobra's `cmd.Println` and `cmd.Printf`, which write to
+  stderr when no output writer is set, so `secret vault list --json | jq`
+  received nothing. "No versions found" from `secret version list` moved to
+  stdout too. Messages such as "Created vault", and the warning after the
+  mnemonic, stay on stderr.
+- 2026-10-14: Removing the current unlocker no longer leaves the vault unable to
+  open through the unlockers it still has
+  (https://git.eeqj.de/sneak/secret/issues/137). `current-unlocker` went on
+  naming the removed unlocker, so every command that opened the vault failed,
+  with advice to use the mnemonic. `secret unlocker remove` of the current
+  unlocker now makes the first of the vault's other unlockers that
+  `secret unlocker select` accepts, in the order `secret unlocker list` shows,
+  current before removing it, and says so; when there is none, it also removes
+  `current-unlocker`. `vault.RemoveUnlocker` returns the ID of the unlocker it
+  made current. When `current-unlocker` names an unlocker that does not exist
+  and the vault has another that `secret unlocker select` accepts, the error
+  wraps `vault.ErrUnlockerNotFound` and says to run `secret unlocker select`,
+  without the advice to use the mnemonic.
+- 2026-10-14: A `secret add --force` that cannot unlock the vault, given a wrong
+  passphrase or mnemonic, leaves the secret as it was
+  (https://git.eeqj.de/sneak/secret/issues/136). The new version used to be
+  written before the vault was unlocked to set `notAfter` on the version it
+  replaces, so each failed add left one more version that `secret version list`
+  showed. The vault is now unlocked, and that version's metadata read, before
+  anything is written. `generate secret --force` and `import --force` take the
+  same path.
 - 2026-10-12: A mnemonic typed with extra spaces, tabs or line breaks gives the
