Rewrite from TypeScript to Go

Complete rewrite of the Freebee Matrix bot as GogoBee using mautrix-go.

- E2EE with goolm (pure Go, no CGo/libolm) and cross-signing bootstrap
- 35+ plugins with dependency injection and ordered registration
- SQLite storage via modernc.org/sqlite (no CGo)
- Scheduler via robfig/cron for WOTD, holidays, birthdays, releases, etc.
- Optional LLM integration (Ollama) for sentiment, profanity, roasts, vibes
- Threaded trivia, three-tier profanity tracking, WOTD usage verification
- Multi-country holiday support with deduplication
- Quadratic XP curve, configurable bot display name, encrypted DMs
