Bug: winsound.PlaySound missing SND_SYNC flag causes sounds to be cut off on Windows

Description

In .claude/hooks/scripts/hooks.py, the play_sound() function on Windows calls winsound.PlaySound without the SND_SYNC flag. The code comment explicitly says SND_SYNC should be used, but the flag is omitted from the actual call.

Affected Code

winsound.PlaySound(str(file_path),
                 winsound.SND_FILENAME | winsound.SND_NODEFAULT)
                 # Missing: | winsound.SND_SYNC

Code Comment vs Reality

The comment directly above this call reads:

# Note: Using SND_SYNC instead of SND_ASYNC because the script exits immediately after this call, which would terminate async playback before it completes

Despite this comment, SND_SYNC is not included in the flags. Without SND_SYNC, winsound.PlaySound defaults to asynchronous playback. Since the script exits right after, the sound is cut off immediately and never plays completely on Windows.

Fix

winsound.PlaySound(str(file_path),
                 winsound.SND_FILENAME | winsound.SND_NODEFAULT | winsound.SND_SYNC)

Impact

Hook sounds never play to completion on Windows — the script exits before the async audio thread finishes.
