feat: phase 3 — config, skills, model groups, task list, and sidebar UI

- Config system: TOML-based dispatch.toml with hot-reload via chokidar
- Model/key resolution: tag-based model selection, key fallback chains
- Skills system: directory loader with TOML frontmatter, agent mappings
- Task list tool: add/update/list/get operations with WebSocket events
- API routes: GET /config, /skills, /skills/:name, /models, /models/resolve
- Frontend: sidebar with model status, task list, config viewer, skills browser, permission log
- Sliding sidebar animation using CSS transitions (not Svelte transitions)
