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)
