feat: Add Claude Code integration plugin (#651)
* feat: Add Claude Code integration plugin

Complete port of hindsight-openclaw (v0.4.19) adapted to Claude Code's
hook-based plugin architecture. Pure Python stdlib, no external dependencies.

- Auto-recall via UserPromptSubmit hook (additionalContext injection)
- Auto-retain via async Stop hook (chunked retention with sliding window)
- Daemon management (auto-start/stop hindsight-embed via uvx)
- Dynamic bank IDs with per-agent/project/channel/user granularity
- All 34 configuration options with env var overrides
- File-based state persistence with fcntl locking
- Graceful degradation on all error paths

Works with Claude Code Channels (Telegram, Discord, Slack) and
interactive sessions.

* fix: Set correct chunked retention defaults (10/2, not 1/0)

retainEveryNTurns=10 and retainOverlapTurns=2 are the production-tested
values — every 10 turns, retain a 12-turn sliding window. The previous
defaults (1/0) would retain every single turn with no overlap, defeating
the chunked retention design that prevents API bombardment.

* fix: Align recallBudget and daemonIdleTimeout with Openclaw defaults

recallBudget: "low" → "mid" (Openclaw default)
daemonIdleTimeout: 300 → 0 (Openclaw default, never auto-stop)

As an official Hindsight integration, defaults should match Openclaw.
Users can optimize locally via settings.json or env vars.
