test(agents): cover Bedrock Converse toolUse arg parsing

[HumphreySun98]

Summary

Bedrock's Converse API returns tool calls shaped as {"toolUseId": ..., "name": ..., "input": {...}} — no function wrapper and no arguments key — so CrewAgentExecutor._parse_native_tool_call must read input. Today it does (func_info.get("arguments") or tool_call.get("input", {})), but this path has no offline coverage: the existing Bedrock tests are gated behind live AWS credentials (RUN_BEDROCK_LIVE_TESTS), leaving the arg extraction unprotected against regression.

This is exactly what #4972 reported (Converse args dropped, every tool receiving {}). The bug is already fixed at main; this PR locks the behavior in.

Tests

Adds two credential-free unit tests to TestNativeToolCallingJsonParseError:

• test_bedrock_converse_tooluse_args_pass_through — a raw Converse toolUse dict yields its input as the args (not {}).
• test_bedrock_converse_tooluse_args_reach_the_tool — those args actually execute the tool with real values.

Both would have failed under the buggy behavior described in the issue.

📝 Walkthrough

Walkthrough

Two regression tests are added to test_native_tool_calling.py for the Bedrock Converse provider. The first test verifies that func_args is extracted from the input field of a toolUse block. The second test verifies those parsed arguments propagate through _execute_single_native_tool_call to produce the expected tool output.

Changes

Bedrock Converse toolUse regression tests

Layer / File(s)	Summary
toolUse argument parsing and execution tests lib/crewai/tests/agents/test_native_tool_calling.py	Adds a unit test asserting func_args is read from the toolUse block's input field rather than defaulting to {}, and an end-to-end test confirming those arguments reach the tool implementation via _execute_single_native_tool_call.
