"""``--in`` accepts Git Bash / MSYS-style paths on Windows.

Under Git Bash, ``hermes chat --in ~`` reaches the native CLI as
``/c/Users/<user>`` — the shell expands ``~`` to an MSYS POSIX path and
MSYS2's automatic argument conversion is disabled for native executables.
The resolver must translate the MSYS/Cygwin/WSL drive-root spellings to
native form before the isdir check, or every Git Bash invocation dies with
"--in directory not found" (hit live by the Bot Mode agent-messaging flow,
whose SOUL protocol tells agents to deliver with ``--in ~``).

The translation itself (``_msys_to_windows_path``) has exhaustive unit
coverage in tests/tools/test_local_env_windows_msys.py; this pins the
``--in`` call site actually applying it.
