Combo mixes models, so non-Claude thinking signatures leak into
conversation history. Native passthrough forwarded them verbatim and
Anthropic rejected the request. Validate signatures and drop invalid
thinking blocks, re-inserting a placeholder when tool_use requires one.

Gemini rejects the non-standard 'deprecated' keyword in nested tool
schemas with INVALID_ARGUMENT (400). Add it to UNSUPPORTED_SCHEMA_CONSTRAINTS
alongside 'optional' so it gets stripped during translation.

Gemini/Antigravity generateContent rejects the JSON Schema annotation
keywords deprecated, readOnly, writeOnly with a 400 INVALID_ARGUMENT.
MCP tool schemas (e.g. Claude Code) commonly set deprecated:true, making
every request with such a tool fail. Add them to
UNSUPPORTED_SCHEMA_CONSTRAINTS so cleanJSONSchemaForAntigravity removes
them recursively before the request is sent.

Strip `type` field and fold `function.{name,description,parameters}` into
top-level {name, description, input_schema} before forwarding to Claude-format
endpoints. MiniMax (and other Anthropic-compatible providers) reject tools
carrying a `type` field with error code 2013 ("invalid tool type").

Remove "pattern" from UNSUPPORTED_SCHEMA_CONSTRAINTS so glob/grep tool
