Initial commit: SenSu Alpha 0.2.0

- 13-service async plugin framework
- Textual TUI with CLI fallback
- Plugin hot-reload + permission system
- Web management panel (aiohttp)
- Bridge-based inter-module communication
- 10 regression tests

Fixes applied:
- PBKDF2-SHA256 auth (was plain SHA256)
- Auth bypass removed (was allow-all on fail)
- Bare excepts replaced with logged errors
- CatFramework/DreamSu -> SenSu naming unified
- ServiceManager: health checks + startup_order
- Env var credentials (SENSU_ADMIN_PASSWORD etc)
