garrytanandcapy-ai[bot] 75e425b1d5 doctor: name the Windows bash gstack resolves and what chose it
On Windows (OSTYPE msys/cygwin) gstack-doctor adds a 'windows bash' row from
lib/script-invocation.ts resolveWindowsBash, run through the new thin
bin/gstack-windows-bash.ts with the bun on PATH: the resolved bash and the
override or discovery step that chose it, a warn when GSTACK_GIT_BASH and
GSTACK_BASH differ, and a fail carrying the BASH_UNAVAILABLE line (every
candidate with its rejection reason) when none qualifies. Tests inject the
platform (GSTACK_DOCTOR_PLATFORM) and the discovery inputs
(GSTACK_DOCTOR_BASH_PROBE) so the row runs on every OS.

/**
* gstack-windows-bash — the doctor's `windows bash` row: the Git Bash gstack's
* TypeScript hands its bash scripts to on Windows, and what chose it
* (lib/script-invocation.ts resolveWindowsBash, the one resolver).
*
* gstack-windows-bash [--probe <file>]
*
* Prints `WINDOWS_BASH: <path>` and `WINDOWS_BASH_SOURCE: <source>` (exit 0),
* or `WINDOWS_BASH_REFUSED: <BASH_UNAVAILABLE line listing each candidate>`
* (exit 1); `WINDOWS_BASH_WARNING: <text>` when GSTACK_GIT_BASH and
* GSTACK_BASH differ. --probe reads the discovery inputs from a JSON file
* ({exists, gitExecPath, which, uname}, the shape of
* test/fixtures/windows-bash-resolution.json) so tests drive it on any OS;
* without it the resolver probes this machine. Exit 2 on usage.
