feat: add Feishu document comment intelligent reply with 3-tier access control

- Full comment handler: parse drive.notice.comment_add_v1 events, build
  timeline, run agent, deliver reply with chunking support.
- 5 tools: feishu_doc_read, feishu_drive_list_comments,
  feishu_drive_list_comment_replies, feishu_drive_reply_comment,
  feishu_drive_add_comment.
- 3-tier access control rules (exact doc > wildcard "*" > top-level >
  defaults) with per-field fallback. Config via
  ~/.hermes/feishu_comment_rules.json, mtime-cached hot-reload.
- Self-reply filter using generalized self_open_id (supports future
  user-identity subscriptions). Receiver check: only process events
  where the bot is the @mentioned target.
- Smart timeline selection, long text chunking, semantic text extraction,
  session sharing per document, wiki link resolution.
