Problem

validate_hook_command always runs bash -n -c <command>:

let mut cmd = std::process::Command::new("bash");
cmd.arg("-n").arg("-c").arg(&command);

On Windows there is no bash on the default PATH (unless Git Bash/WSL is installed), so the command fails with Failed to validate command: ... program not found and the hooks editor cannot validate anything.

Change

On Windows, skip the syntax check and return valid: true with a short message, instead of erroring out. The hook is still executed by whatever shell the user configured; this only affects the optional syntax pre-check.

Notes

• Non-Windows behavior is unchanged;
• If you prefer a real check on Windows, a follow-up could use powershell -NoProfile -Command "[scriptblock]::Create($cmd)", but hooks are often bash syntax, so skipping is the safer default.
