Replace in-memory storage with SQLite (WAL mode), add workspace-based
multi-tenancy with auto-detection via server.listRoots(), and embed the
canvas server into the MCP process for single-process operation.
🔧 Core enhancements:
- SQLite persistence with versioning, element history, and search
- Multi-tenancy: isolated canvases per workspace (SHA-256 tenant IDs)
- Embedded canvas lifecycle (single node process starts MCP + canvas)
- Auto-sync with 3s debounce and manual override toggle
- Configurable canvas port via CANVAS_PORT env var
- 6 new MCP tools (search, history, tenants, projects)
- Workspace switcher UI with dropdown search
- Sync normalization to prevent bound-text breakage on reload
🐳 Docker & CI improvements:
- BuildKit cache mounts for faster npm installs across builds
- Skip native compilation in frontend-builder stage (--ignore-scripts)
- Build only linux/amd64 on PRs, multi-arch on push to main
- Docker Hub registry with proper build tools for better-sqlite3
- CI and Docker status check gates (github/ci-status-check, github/docker-build-check)
📦 Package & publishing:
- Renamed to @sanjibdevnath/mcp-excalidraw-local (v3.0.0)
- Updated npm-publish workflow for scoped package
- Updated bin entry, keywords, and files list
📝 Documentation:
- README with UI screenshots, architecture diagram, and full feature docs
