refactor(hooks): address PR feedback

- Rename getTools/setTools to getActiveTools/setActiveTools
- Add getAllTools to enumerate all configured tools
- Remove text_delta event (use turn_end/agent_end instead)
- Add shortcut conflict detection:
  - Skip shortcuts that conflict with built-in shortcuts (with warning)
  - Log warnings when hooks register same shortcut (last wins)
- Add note about prompt cache invalidation in setActiveTools
- Update plan-mode hook to use agent_end for [DONE:id] parsing
