REM Cross-platform polyglot wrapper for hook scripts.
REM On Unix: POSIX shells execute the ":;" lines above and exec away before
REM reaching this batch block (":" is a no-op; cmd.exe treats lines starting
REM with ":" as labels and skips them). If bash or the script name is
REM missing, the wrapper exits 0 silently - hooks are optional context, never
REM a session breaker.
REM On Windows: cmd.exe runs this batch portion, which finds and calls bash.
REM
REM Heredocs are banned in this file and every hooks/ executable: bash 5.1+
REM delivers them via a pre-fork pipe write that deadlocks on macOS under
REM pipe pressure (issue #571). tests/hooks/test-no-heredocs-in-hooks.sh is
REM the fence.
REM
REM Hook scripts use extensionless filenames (e.g. "session-start" not
REM "session-start.sh") so Claude Code's Windows auto-detection -- which
REM prepends "bash" to any command containing .sh -- doesn't interfere.

REM Usage: run-hook.cmd <script-name> [args...]
