Lucas Kim c00e3228fc fix(bedrock): preserve streaming tool call arguments at contentBlockStop (#6150)
* fix(bedrock): preserve streaming tool call arguments at contentBlockStop

Streaming Converse handlers accumulate tool input as JSON string deltas in
accumulated_tool_input but never fold it back into current_tool_use["input"],
so function_args reads an empty {} at contentBlockStop. Parse the accumulated
input into the tool-use block (with a {} fallback) in both the sync and async
streaming handlers. This is the streaming counterpart of the non-streaming fix
in #5415 (issue #4972).

* fix(bedrock): coerce non-dict streaming tool input to empty dict

json.loads on the accumulated tool input can return a valid-but-non-object
JSON value (e.g. a string or list), which would fail at fn(**function_args)
with a TypeError. Enforce a dict shape before use in both the sync and async
streaming handlers, and add a regression test for the non-dict case.

Addresses CodeRabbit review feedback on #6150.
