feat(Mountain): Enable core Mountain module structure

- Uncommented all Mountain backend modules in Library.rs to establish foundational code structure
- Activated `app_state` and `environment` for central state management and runtime environment setup
- Enabled `handlers` module with submodules covering commands, config, diagnostics, storage, and workspace operations critical for MVP
- Exposed `track` (dispatcher), `vine` (IPC), `rpc`, and `mist` (networking) modules to enable core backend functionality
- Prepared `protocol`, `process_mgmt`, and `workspace_fs_api` modules for VS Code extension compatibility via Cocoon shim

This structural enablement creates the scaffolding required for:
- Command routing through Track dispatcher
- State persistence via AppState
- IPC communication with Cocoon extension host
- Native filesystem operations through workspace_fs_api
- Future implementation of VS Code-compatible RPC protocols
