fix(anthropic): drop the non-spec custom object from /v1/messages tool definitions (#48893)
* fix(anthropic): drop the non-spec custom object from /v1/messages tool definitions

Anthropic and Vertex AI reject a tool carrying a custom object with tools.N.custom.custom: Extra inputs are not permitted. Drop it on the shared Anthropic request path, keep the hoist of a boolean custom.defer_loading to top-level defer_loading, reuse the helper on Bedrock, and stop the chat adapter from merging custom into the tool's JSON schema

* fix(messages): hoist custom.defer_loading only on Claude routes and strip custom on count_tokens

Non-Claude Messages providers such as DeepSeek now get custom dropped without a defer_loading hoist, since they have no tool search. /v1/messages/count_tokens on Anthropic, Azure AI, and Vertex AI drops custom too, and the local token counter no longer counts it as schema.

* fix(anthropic): drop tool custom object only under drop_params and hoist defer_loading for Claude models

Without drop_params the tool is forwarded as sent, so the provider's 400 stands. A boolean custom.defer_loading still becomes the top-level flag for Claude models and on Bedrock Invoke and Mantle. Bedrock count_tokens now normalizes invokeModel tools the way Bedrock Messages sends them.

* fix(bedrock): drop tool custom object on the Mantle count_tokens fallback

Mantle Messages drops custom unconditionally, so its count_tokens call now counts the tools the same way.

* fix(messages): keep custom-tool Messages calls on Python and match Mantle count_tokens to Mantle Messages

* test(vertex): annotate count_tokens tool test locals with Final

* fix(messages): pass tools without custom through untouched so Bedrock fallbacks keep filled tool names

* fix(messages): keep Bedrock's in-place tool cleanup so fallbacks still work, and stop hoisting defer_loading on the OpenAI-like passthrough

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.
