upsert vectors, and query by semantic similarity. Uses @pinecone-database/mcp.

https://claude.ai/code/session_013AxurW8hPAfnUNvik354Xx

* fix: update server definition (input type 'password' -> 'text' for PINECONE_API_KEY)

* fix: rename server files with transport suffix

- io.pinecone-mcp.json -> io.pinecone-mcp-npx.json (id: io.pinecone-mcp-npx)
