fix(vertex_ai): prevent Gemini from misinterpreting $ref in tool results (#38284)
* fix(vertex_ai): prevent Gemini from misinterpreting $ref in tool results

* fix(vertex_ai): use object instead of Any in schema-ref traversal

* fix(vertex_ai): use immutable tuple traversal to satisfy type-discipline gate

* test(vertex_ai): add direct contract test for _contains_json_schema_ref

* fix(vertex_ai): type the $ref walk over JsonValue and drop the private-helper test

* fix(vertex_ai): wrap a tool result only when a $ref holds a non-empty string

Gemini rejects {"$ref": "<name>"} in function_response.response but accepts null, empty,
numeric, boolean, object, and list values, so those tool results stay structured

* perf(vertex_ai): skip the $ref walk when the tool result text cannot spell the key

* test(vertex_ai): cover a $ref on the tool result's root object

* docs(vertex_ai): cite where the Gemini $ref rule was observed

* fix(vertex_ai): keep a $ref under a list of lists structured

Gemini accepts a $ref reached through a list nested directly in a list,
so those tool results keep their structured form. Adds the audit's
integration cells for the tool result wire, chaos and edge shapes

* test(vertex_ai): teach the fake Gemini servers the list of lists rule

The audit's scripted upstreams now skip lists inside a list like Gemini
does, add list of lists cells on every endpoint, and give the 8 MiB
timing calls their own client timeout

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/unit

This folder can only run mock tests.
