fix(gemini): add thought_signature_in_tool_call_id to keep tool call ids short for clients that cap them (#47692)
* test(e2e): add gemini tool call id length repro for LIT-8912

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(gemini): add thought_signature_in_tool_call_id to keep tool call ids short for clients that cap them

* fix(gemini): pair a tool result with its call when the client re-adds the thought signature to the call id

Strands, which the AgentCore harness runs, puts provider_specific_fields.thought_signature back on the
assistant tool call id as <id>__thought__<signature> while its tool result keeps the bare id, so the Gemini
conversion found no matching call and answered 500. Ids now match with the signature suffix stripped.

Also adds thought_signature_in_tool_call_id to the litellm_params inventory test and gives the pass-through
tests' mocked logging objects the litellm_params a real Logging object always has.

* fix(gemini): keep the thought signature on streamed Messages and Responses tool calls and accept a string setting

* fix(gemini): read the thought signature back from Responses input and coerce the per-request setting

A Responses function_call input item now keeps its provider_specific_fields, so a
client that sends the item back gets its real thought signature replayed to Gemini.

A per-request thought_signature_in_tool_call_id of "false" or 0 now keeps ids short,
and a value that is not a boolean answers 400, or is dropped under drop_params,
instead of a 500.

The e2e test now uses the sdk fixture and @meta subjects

* fix(caching): key the response cache on thought_signature_in_tool_call_id

* fix(responses): send thought signature fields only with short ids and drop malformed routing kwargs whole

* fix(main): validate routing kwargs after the locals snapshot so fallbacks and model_list calls keep working

The e2e test now uses gemini-3.8-flash with enough max_tokens to finish thinking before the tool call.

* fix(gemini): keep non-chat routes tolerant of a malformed thought_signature_in_tool_call_id, match tool results by exact id first, and keep the deployment's value when drop_params drops a malformed override

* fix(router): validate strict litellm params through a helper so star imports cannot re-bind a public Final

* perf(router): skip strict validation when a request overrides no deployment param

* fix(responses): keep a dict tool call's thought signature on the streamed function_call done item

* refactor(main): return invalid supplemental params as a value and test the streaming tool call with a real response
