/**
 * Regression test for bug #580.
 *
 * LOCAL install under Claude Code on Windows: managed `.sh` hooks were emitted
 * wrapped with an absolute `bash.exe` path via the `localShellCmd` arrow.
 * Since Claude Code runs hook command strings INSIDE Git Bash, bash tries to
 * exec bash → "cannot execute binary file".
 *
 * The GLOBAL path (`buildHookCommand`) already guarded win32+claude+.sh (#166).
 * The LOCAL path (`localShellCmd`) did not. Fix: add `buildLocalShellHookCommand`
 * and `shellHookOmitsBashRunner` to shell-command-projection.cjs, and use
 * `buildLocalShellHookCommand` from install.js local-install path.
