fix: deep audit round 2 — non-streaming mode config + ClarificationCard + settings restructure

HIGH fixes:
- H-NS-1: Non-streaming agent_chat now builds ChatModeConfig and calls
  send_message_with_chat_mode(), matching the streaming path
- H-FE-1: ClarificationCard component renders structured clarification
  questions with type badge, question text, and numbered options
- H-SEM-1: SemanticSkillRouter annotated as @reserved (Phase 3 wiring)

MEDIUM fixes:
- M-SETTINGS-1: Settings menu restructured with "高级" section separator;
  skills/audit/tasks/heartbeat/semantic-memory grouped under advanced
- M-MAN-1: LoopEvent→StreamChatEvent mapping completeness checklist
  added as documentation comment in agent_chat_stream loop
- M-ORPH-1: Deleted orphaned Automation/ and SkillMarket/ files,
  plus transitively orphaned types, hooks, and adapters
