fix: sync cache on install, copy all hook files to live 0.1.0 cache

install.sh now copies hooks-handlers/*.py and hooks.json into the live
cache dir after symlinking — ensures edits take effect in the running
session without a CC restart for hook scripts, and on next session start
for hooks.json changes.

Also manually synced 0.1.0 cache to unblock current session:
- post-tool-use.py: find_catalog + already-owned spawn guard
- user-prompt-submit.py: null buddymon_id fallback
- roster-stop.py: reads roster_output.txt (no recursive CLI call)
- hooks.json: roster-stop.py Stop hook entry

install.sh
