Expand sentiment to 10 categories, add DB maintenance job, update README

- Expand LLM sentiment classification from 3 to 10 categories: positive,
  negative, neutral, excited, sarcastic, frustrated, curious, grateful,
  humorous, supportive — with emoji reactions for each
- Add daily DB maintenance job at 03:00 UTC to purge stale caches,
  expired rate limits, old logs, and run SQLite optimize
- Add migrate.sql for upgrading existing databases
- Update README: add !sentiment command, maintenance job, rate limit
  config, in-memory message buffer docs, SDK migration history,
  remove references to previous private repo
