Windows Proxy and Cloud Update
Add Ollama proxy, offline UI, export, cloud sync APIs, and auth hardening
- Ollama transparent proxy on :11435 intercepts token counts from third-party apps and logs to ~/.trace/ollama_proxy.jsonl; proxy status exposed via /api/system/proxy-status
- Stronger provider auto-detection: platform-specific default paths and running-process detection via subprocess
- Offline/skeleton UI: Zustand serverStore, OfflineBanner, skeleton cards when server is unreachable, persistent offline toast
- Toast notifications for provider detection, provider connect/disconnect
- Export endpoints: GET /api/export/json and /api/export/csv with range filtering; Export Data card in Settings
- Cloud sync local APIs: /api/cloud/account, /api/cloud/token, /api/cloud/logout, /api/cloud/sync; cloud_synced_at column on Request; watcher auto-syncs on each tick; AccountPage with login/logout UI
- Electron deep-link: registers trace:// protocol, handles open-url (macOS) and second-instance (Windows), forwards JWT to renderer; exposes openCloudLogin and onCloudAuthCallback via preload
- Auth hardening: credential format validators in auth.py, trace-cloud provider added
- Model art: added CodeLlama, Phi, Falcon, StarCoder, Cohere family rules
