refactor: turn_end_callback + desktop pet + keychain

- agent_loop: next_prompt_patcher -> turn_end_callback with full context
- agent_loop: exit logic unified (break + callback), no early return
- ga: summary extraction moved from tool_after_callback to turn_end_callback
- ga: _turn_end_hooks support for external subscribers
- stapp: desktop pet button with HTTP status push
- keychain: XOR-masked secret storage with SecretStr
- gitignore: whitelist keychain.py
