The MCP spec only permits 'text', 'image', 'audio', and 'resource' as
content types. MCPSearchServlet was returning {"type":"json","json":{...}}
which caused MCP clients (e.g. Claude Code) to reject the response with
a schema validation error. Changed to {"type":"text","text":"..."} with
the payload serialized as a JSON string.

- Normalize Solr scores per peer batch before inserting into the shared priority queue so results from different peers compete on a [0,1] scale rather than on their raw absolute scores, which vary widely across indexes - Add a Language dropdown to the search form with 11 common languages - Persist the selected language in a yacy-language cookie (1 year) so users no longer need to manually append /language/en to every query - Fall back to cookie preference when no explicit lr param is submitted; selecting "any" clears the cookie and removes the filter Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
