* fix(gemini): normalize response_schema on native generateContent
The /v1beta/models/{model}:generateContent passthrough forwarded
generationConfig.response_schema verbatim, so schemas containing $defs,
$ref, anyOf-with-null, default, or title were rejected by Gemini even
though /chat/completions already handles them.
GoogleGenAIConfig.transform_generate_content_request now calls a new
_normalize_response_schema helper that mirrors the chat/completions
path: Gemini 2.0+ models get the schema promoted to responseJsonSchema
via _build_json_schema (preserving $defs/$ref natively), older models
keep responseSchema but the schema is flattened with
_build_vertex_schema. VertexAIGoogleGenAIConfig (which overrides the
transform entirely) calls the same helper before building the request.
* fix(gemini): preserve caller-supplied responseJsonSchema when responseSchema co-present
Previously, when both responseJsonSchema and responseSchema were present
on Gemini 2.0+, _normalize_response_schema processed responseJsonSchema
first (no-op normalization) then unconditionally promoted responseSchema
to responseJsonSchema, clobbering the caller-supplied value.
Now skip the promotion (and drop the redundant responseSchema) when the
caller already supplied responseJsonSchema.

* chore: strip restating comments from response-schema normalize
Drop the docstring on _normalize_response_schema and the two inline
comments that just restated what the surrounding code/asserts already
say. Function name + variable names carry the intent; PR description
covers the why-it-exists context.
* perf(gemini): drop redundant deepcopy on responseJsonSchema normalize
_build_json_schema is a no-op (returns its argument unchanged), so the
deepcopy + round-trip on the responseJsonSchema branch allocated a full
schema copy on every request with no observable effect. Forward the
caller's value as-is, and just move the popped responseSchema value when
promoting on Gemini 2.0+.

* style: remove unneeded comment
* fix(gemini): drop unsupported responseJsonSchema for older models
* test(gemini): add parity test between native and chat schema normalization
Per @Sameerlite review: lock the two Gemini schema-normalization paths
together. If either GoogleGenAIConfig._normalize_response_schema (native
generateContent) or VertexGeminiConfig.apply_response_schema_transformation
(/chat/completions) drifts, the parity test fails — forcing both to be
updated together.
* fix(google_genai): preserve key naming convention in _normalize_response_schema
When the input schema key is snake_case (response_schema), the promoted
JSON schema key should also be snake_case (response_json_schema) instead
of mixing in camelCase (responseJsonSchema). This matters for the Vertex
AI google_genai path which converts all keys to snake_case before
calling _normalize_response_schema.

Testing for litellm/
This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.
The point of this is to:
- Increase test coverage of
litellm/ - Make it easy for contributors to add tests for the
litellm/package and easily run tests without needing LLM API keys.
