fix(vertex_ai): unwrap tool-emulated json_schema envelopes and send output_config.format for Claude (#45871)
* fix(vertex_ai): unwrap tool-emulated json_schema envelopes and send output_config.format for Claude

Vertex AI Claude deployments that emulate response_format through a forced
tool sometimes nest the schema object under an extra key such as
`parameters` or `input`, and that envelope reached message.content with a
200. The converter now unwraps exactly one nested object that matches the
schema, leaving a payload that is itself schema-shaped alone.

Native structured-output rows sent the deprecated top-level `output_format`,
which Vertex rejects with a 400. The Vertex request now carries it as
`output_config.format`, with an explicit caller value winning.

* fix(anthropic): unwrap tool-emulated json_schema envelopes on streams and tool-name wrappers

* test(anthropic): expect the json tool description through a shared constant

* fix(anthropic): drop the json tool description that makes sonnet-5 omit required keys

* fix(anthropic): keep schema-accepted answers whole and decide held streams at the second key

An answer the json_schema accepts is returned as is before any envelope rule runs, the tool-name
wrapper is unwrapped only when the schema rejects it, a malformed schema turns the unwrap off, a
streamed answer whose first key is a schema property named name or tool_name waits for its second
key before streaming, the held fragments go through a StringIO, and a prefix that stays undecided
past 4 KB is held to the end

* test(anthropic): keep the stream family cells to providers whose stream iterator gets the schema

* fix(anthropic): unwrap json tool envelopes by structure instead of schema validation

The unwrap now reads only the schema's top-level property names. A lone
undeclared key holding an object, alone or beside a name equal to the json
tool's own name, is the envelope, and the unwrap repeats while the inner
object shares no key with the schema. jsonschema and referencing are no
longer imported on the request path. The stream holds only an answer that
opens with the tool's name or with an undeclared key holding an object, and a
schema without top-level properties streams as it arrives.

* fix(anthropic): walk json tool envelopes iteratively

* fix(anthropic): keep json tool arguments too deep to decode instead of raising

* fix(anthropic): unwrap json tool envelopes beside undeclared string labels

* fix(anthropic): keep json answers whole on schemas that allow extra keys and stream held text as sent

A schema that allows undeclared keys and requires none now keeps an undeclared wrapper key on both the stream and non-stream paths. When no envelope is found, the held stream text is now sent exactly as the model wrote it. On Vertex /v1/messages, output_format now wins over output_config.format when both are set, which matches the Anthropic adapter.

* test(anthropic): cover label envelopes, dynamic-key schemas, as-written held streams and output_format precedence

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.
