v0.3.14

Fixed

• MCP server instructions: incorrect parameter names — The consolidated tools summary in the MCP server instructions advertised type= for source_add, studio_create, and download_artifact, but the actual tool schemas use source_type and artifact_type. AI clients reading the instructions would use wrong parameter names, causing validation errors. Also added value parameter hints for source_add.
• Changelog credit — Credited @byingyang for identifying the notebook operations routing bug (PR #61).
