* fix(vertex_ai): route google/gemma-*-maas through partner-models OpenAI path

Fixes #26083

vertex_ai/google/gemma-4-26b-a4b-it-maas previously fell through to the
NON_GEMINI route. Per owtaylor's plan on #26083: add the google/gemma-
prefix to PartnerModelPrefixes so is_vertex_partner_model picks it up
and should_use_openai_handler routes it to the OpenAI-compatible
/endpoints/openapi/chat/completions URL. No gemma-detection exclusion
needed (the "gemma/" check uses a slash, which google/gemma-... doesn't
match). No OpenAIGPTConfig subclass needed — works with the base handler.

* fix(vertex_ai): mark gemma-4-26b-a4b-it-maas as vision-capable (empirically verified)

* fix(vertex_ai): address greptile feedback — provider category, canonical URL, sync backup

* test(vertex_ai): add function-calling and vision pass-through tests for Gemma MaaS

   Addresses oss-pr-review-agent-shin feedback on PR #28010:
   supports_function_calling, supports_tool_choice, and supports_vision were
   marked true but had no tests proving the payloads actually reached the
   OpenAI-compatible endpoint.

   Added:
   - test_gemma_maas_supports_function_calling — verifies the utility returns True
     when the model_cost entry carries supports_function_calling=true
   - test_gemma_maas_supports_vision — same for supports_vision
   - test_vertex_ai_gemma_function_calling_passthrough — verifies tools + tool_choice
     appear in the JSON body POSTed to /endpoints/openapi/chat/completions
   - test_vertex_ai_gemma_vision_passthrough — verifies image_url content parts
     survive transformation and reach the global endpoint URL

* fix: Delete uv.lock

* test(vertex_ai): add function-calling and vision pass-through tests for Gemma MaaS

Addresses oss-pr-review-agent-shin feedback on PR #28010:

   P1 (patch target): Added a comment explaining why patching
   litellm.llms.custom_httpx.http_handler.AsyncHTTPHandler is correct —
   get_async_httpx_client() (defined in http_handler.py) instantiates
   AsyncHTTPHandler within that module's scope, so the definition-site patch
   intercepts it. Without the mock the test raises AuthenticationError,
   confirming it never silently passes.

   P2 (partner-provider regression guard): Added
   test_gemma_routes_through_openai_handler() which calls
   VertexAIPartnerModels.should_use_openai_handler() directly, so if Gemma's
   routing to VertexPartnerProvider.llama ever changes the URL-shape tests
   below it become a real regression guard rather than an unanchored unit test.

   Also added:
   - test_gemma_maas_supports_function_calling / supports_vision — capability
     flag checks via patch.dict(litellm.model_cost)
   - test_vertex_ai_gemma_function_calling_passthrough — tools + tool_choice
     forwarded in the request body
   - test_vertex_ai_gemma_vision_passthrough — image_url part survives
     transformation to the global endpoint
   Added:
   - test_gemma_maas_supports_function_calling — verifies the utility returns True
     when the model_cost entry carries supports_function_calling=true
   - test_gemma_maas_supports_vision — same for supports_vision
   - test_vertex_ai_gemma_function_calling_passthrough — verifies tools + tool_choice
     appear in the JSON body POSTed to /endpoints/openapi/chat/completions
   - test_vertex_ai_gemma_vision_passthrough — verifies image_url content parts
     survive transformation and reach the global endpoint URL

* fix: proper patch for unit tests

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/test_litellm

This folder can only run mock tests.
