feat: add Weaviate MCP server definition (#83)

* Add Weaviate MCP server definition

Official Weaviate MCP server for vector database operations. Manage collections,
insert data, and run vector/hybrid searches. Uses mcp-server-weaviate via uvx.

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

* fix: rename server files with transport suffix

- io.weaviate-mcp.json -> io.weaviate-mcp-uvx.json (id: io.weaviate-mcp-uvx)
