/**
 * antigravity/gemini returned [400] "Invalid JSON payload received.
 * Unknown name \"encrypted\" at 'request.tools[0].function_declarations[11].
 * parameters.properties[0].value': Cannot find field."
 *
 * Root cause: Codex's multi-agent collaboration tools (spawn_agent /
 * send_message / followup_task) mark their `message` parameter schema with a
 * non-standard `encrypted: true` annotation (JsonSchema::with_encrypted).
 * `encrypted` was NOT listed in `GEMINI_UNSUPPORTED_SCHEMA_KEYS`, so
 * `cleanJSONSchemaForAntigravity` left it in the function-declaration
 * parameters, and the Gemini/antigravity upstream (OpenAPI 3.0 schema subset)
 * rejects the unrecognized keyword with a hard 400. This only shows up when
 * routing Codex to an agy/Antigravity model because the OpenAI passthrough
 * path does not validate tool schemas.
 *
 * Fix: add `encrypted` to the unsupported-keys set so it is stripped at every level.
