Gemini's function_declarations validator requires:
- ARRAY types must declare items schema
- Free-form OBJECT (without properties) is rejected
Renamed free-object params to *Json string fields (envsJson, patchJson,
headersJson) and added server-side JSON.parse before forwarding to MCP.
Any param ending in "Json" is automatically unpacked into its real key
(e.g. envsJson string is parsed into envs object).
