fix(server.json): use standard runtimeHint and packageArguments format

Update server.json to follow the official MCP Registry specification:
- Use `runtimeHint: "uvx"` instead of embedding command in transport
- Use `packageArguments` for the stdio positional argument
- Add explicit `registryBaseUrl` for PyPI

This format is more compatible with MCP clients and the registry.
