feat: remove like event (unreliable via INTERACT_WORD_V2); restore portable build dir

- Drop 'like' event from rules, handler and web UI (Bilibili like messages
  are not reliably delivered as INTERACT_WORD_V2 msg_type=6)
- Keep enter_room / follow / interact_other
- event_rules.json rewritten without like key
- build.py keeps BUILD_DIR = dist/portable
