feat(api): add Lovart-style project and agent thread endpoints

Add canva/canda-compatible routes for lightweight project open/save and agent thread history: - POST /canva/project/queryProject, saveProject - POST /canva/agent/queryAgentLastThread, agentThreadList - GET /canda/chat-history, /canda/thread/status Canvas save now accepts a compressed SHAKKERDATA:// snapshot payload, preserves connections, and returns a SaveProject response; blank successful image nodes are backfilled from generated artifacts. Frontend designGateway adopts the new save/query flow. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
