feat(hooks): integrate Claude Code hooks with plugin system

- Create factory function createClaudeCodeHooksHook()
- Wire tool.execute.before → executePreToolUseHooks
- Wire tool.execute.after → executePostToolUseHooks
- Wire event (session.idle) → executeStopHooks
- Register hooks in src/index.ts
- Claude hooks execute first in handler chain
