fix(collector): 기능 누락 3건 수정 — Discord 명령어/채팅/등록 중계

Gap 1: Discord→Extension 명령어 깨짐
  - bot.py: _write_command() 래퍼 — gateway.push_command()도 호출
  - main.py: bot.gateway 연결
  - 슬래시 명령어 + on_message 모두 _write_command 사용

Gap 2: Chat snapshot 미전달
  - collector.py: _forward_chat_snapshots_loop 추가

Gap 3: Session registration 미전달
  - collector.py: _forward_registrations_loop 추가
