Subject: [PATCH] Fix search_documentation: call renamed downstream docs MCP
 tool

The docs MCP at planetscale.com/docs/mcp renamed its search tool from
SearchPlanetScale to search_planet_scale and dropped the version,
language, apiReferenceOnly, and codeOnly arguments (its input schema now
only accepts query). The wrapper still called the old name, so every
search_documentation call failed with 'Tool SearchPlanetScale not
found' (-32602). Call the current tool name and pass only query; remove
the now-defunct filter params from the wrapper's input schema.
