chore: remove AI session/chat/sync code and MCP references (#168)

Strip out all AI-agent infrastructure that is not part of the spec
coding framework:

- Delete core modules: sessions, ai, ai_native, models_registry, db
- Delete storage chat modules: chat_store, chat_config
- Delete CLI commands: agent, session, runner, skill
- Remove AI tool detection and MCP config from init command
- Delete HTTP handlers: sessions, chat, models_registry, sync
- Remove sync_state cloud sync from projects handler
- Remove database dependency (sqlx) and AI provider deps (anthropic,
  async-openai, reqwest, schemars)
- Simplify AppState to only hold config, registry, watcher
- Update Cargo.toml features: remove ai, sessions; keep storage, git
- Remove session/runner TypeScript bindings export
- Mark removed-feature init tests as ignored
