feat(events): expose native tool call ids

[z2Ace0107]

Fixes #7178

Summary

• Add an optional call_id field to ToolUsageEvent.
• Populate it for started, finished, and error events emitted by native tool execution paths.
• Preserve backward compatibility for event producers that do not have a native model call id.

This allows event consumers to correlate a tool execution with the model tool call that initiated it.

Verification

• Added regression coverage for successful and failing native tool calls.
• Python 3.12.13: focused native tool tests passed.
• Ruff check passed.
• Ruff format check passed.
• Mypy passed for the changed production files.

Additional context

This PR was prepared with AI assistance. I reviewed the changed implementation and tests. Please apply the required llm-generated label.

📝 Walkthrough

Walkthrough

Changes

Native tool execution now separates provider call IDs from locally generated message IDs. Tool usage events report provider IDs when available. Tests cover successful, failed, missing-ID, and parallel execution paths.

Native tool call ID propagation

Layer / File(s)	Summary
Call ID contract and extraction lib/crewai/src/crewai/events/types/tool_usage_events.py, lib/crewai/src/crewai/utilities/agent_utils.py	ToolUsageEvent now defines optional call_id data. Utilities extract provider IDs from supported tool-call shapes and retain generated fallback IDs for tool messages.
Native tool executor wiring lib/crewai/src/crewai/agents/crew_agent_executor.py, lib/crewai/src/crewai/experimental/agent_executor.py, lib/crewai/src/crewai/utilities/agent_utils.py	Native execution parses and threads provider IDs through single and batched paths. Lifecycle events use provider IDs instead of local fallback IDs.
Event correlation coverage lib/crewai/tests/agents/test_agent_executor.py, lib/crewai/tests/agents/test_native_tool_calling.py, lib/crewai/tests/utilities/test_agent_utils.py	Tests verify provider ID propagation, error events, missing provider IDs, generated message IDs, and distinct IDs for multiple provider-less calls.

Merge Risk: ⚪ Minimal · up to e7a70

This change adds an optional tool-call identifier to tool usage events for native executions while retaining compatibility when providers do not supply an ID. No concrete merge-blocking risk remains.

@z2Ace0107 Thanks for picking this up ,the coverage is broader than I described. I pointed only at _execute_single_native_tool_call, you also caught the emit sites in agent_utils.py and experimental/agent_executor.py.
One gap before it lands. _parse_native_tool_call is unchanged, so it still does:

call_id = getattr(tool_call, "id", f"call_{id(tool_call)}")

The new call_id is therefore sometimes the provider's id and sometimes a value CrewAI invented, with nothing distinguishing them. The synthesized branch derives from id(tool_call) - the object address - which CPython reuses after garbage collection, so two distinct tool calls in a long-running crew can be emitted with the same call_id. A consumer trusting it as a correlation key mis-pairs in exactly the retry and parallel-batch cases the field exists to disambiguate.

Smallest fix (my own suggestion): populate call_id only when the provider supplied one. The semconv treatment for gen_ai.tool.call.id is "when available" - absence is a valid answer, a fabricated id isn't.
Otherwise keep the fallback and add a source marker.

Do the new tests cover the no-provider-id path? From the diff they look like they exercise cases where an id is present

Also, I've accidentally closed the issue by mistake.. Could a maintainer flip back open #7178? It shouldn't read as resolved while this is still in review.

that performs two provider-less tool calls and captures their fallback local
IDs, asserting both use the expected call_ prefix and are distinct. Also verify
each resulting tool message reuses its corresponding local ID, covering
