fix(cli-resolvers): find CLIs installed via nvm/Homebrew when running as a service

Browse Source 
A CLI installed by nvm, Homebrew or a user-level npm prefix lives on a PATH that
only a login shell sets up. Codeman running under systemd or launchd does not get
that PATH — launchd hands a job `/usr/bin:/bin:/usr/sbin:/sbin` — so every
resolver reported the CLI as unavailable on installs where it is plainly there
and works from a terminal.

Each of the six resolvers had its own hand-rolled copy of the same PATH walk, so
the fix is factored into one shared `createCliExecutableResolver()` with an
explicit lookup order: the server process PATH, then common install directories in
order, then an interactive login shell as the last resort. Only the last step
spawns anything, and only when the cheap lookups have already missed.

Also adds `formatCliNotFoundMessage()`, so a failure explains where it looked
instead of just asserting the CLI is missing. Its diagnostics are bounded and
control characters are flattened, so a not-found message cannot dump arbitrary
environment data.

Success is cached and failure is retried, so installing a CLI while the server is
running is picked up without a restart.

Net -103 lines across the six resolvers. Behaviour is unchanged wherever the CLI
was already on the process PATH: that remains the first thing checked.

Tests: 20 cases in test/cli-executable-resolver.test.ts covering the precedence
order, login-shell-only resolution, the caching rule, unsafe-name rejection, and
the bounded diagnostics.
