Subject: [PATCH] fix: replace prompt-type Stop hook with command-type to
 prevent infinite loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Stop hook used "type": "prompt" with an empty matcher, which caused an
infinite loop: Claude responds to evaluate the condition → that triggers Stop
again → hook fires again → repeat forever.

Changes:
- Stop hook: changed to "type": "command" that checks git diff for actual
  wiki/ file changes before outputting anything. Silent exit = no loop.
- SessionStart: added matcher "startup|resume" so it only fires on relevant
  events, plus a command hook to cat hot.md directly.
- Added PostCompact hook to re-inject hot cache after context compaction.
- Added PostToolUse hook to auto-commit wiki changes on Write/Edit.
