Feature 1: Split dirigent_tools
- Replace monolithic dirigent_tools (9 actions) with 9 individual tools
- Discord: dirigent_channel_create, dirigent_channel_update, dirigent_member_list
- Policy: dirigent_policy_get, dirigent_policy_set, dirigent_policy_delete
- Turn: dirigent_turn_status, dirigent_turn_advance, dirigent_turn_reset
- Extract shared executeDiscordAction() helper
Feature 2: Human @mention override
- When humanList user @mentions agents, temporarily override turn order
- Only mentioned agents cycle, ordered by their turn order position
- Original order restores when cycle returns to first agent or all NO_REPLY
- New: setMentionOverride(), hasMentionOverride(), extractMentionedUserIds()
- New: buildUserIdToAccountIdMap() for reverse userId→accountId resolution
Bump version to 0.3.0
Turn system redesign:
- Turn order auto-populated from config bindings (all bot accounts)
- No manual turnOrder config needed
- Humans (humanList) excluded from turn order automatically
- Dormant state: when all agents NO_REPLY in a cycle, currentSpeaker=null
- Reactivation: any new message wakes the system
- Human message → start from first in order
- Bot not in order → start from first
- Bot in order → next after sender
- Skip already-NO_REPLY'd agents when advancing
Identity injection:
- Group chat prompts now include agent identity
- Format: '你是 {name}（Discord 账号: {accountId}）'
Other:
- Remove turnOrder from ChannelPolicy (no longer configurable)
- Add TURN-WAKEUP-PROBLEM.md documenting the NO_REPLY wake-up challenge
- Update message_received to call onNewMessage with proper human detection
- Update message_sent to call onSpeakerDone with NO_REPLY tracking
