* fix(agent): pass tool_call_timeout to SubAgent handoff execution
- Add tool_call_timeout parameter to _execute_handoff method
- Pass run_context.tool_call_timeout to ctx.tool_loop_agent
- Add unit test to verify tool_call_timeout is correctly passed
- Fixes#6711: SubAgent MCP tool call timeout now respects configured timeout
The SubAgent handoff execution was using the default 60-second timeout
instead of the configured tool_call_timeout from provider settings.
This change ensures that SubAgent MCP tool calls respect the user's
configured timeout settings.
* test: add unit test for tool_call_timeout in SubAgent handoff
* fix: restore deleted test and fix test assertion
- Restore test_collect_handoff_image_urls_filters_extensionless_missing_event_file
- Fix test_collect_handoff_image_urls_keeps_extensionless_existing_event_file assertion
- Keep new test_execute_handoff_passes_tool_call_timeout_to_tool_loop_agent
* refactor: simplify tool_call_timeout passing in _execute_handoff
- Pass run_context.tool_call_timeout directly to ctx.tool_loop_agent
- Remove unnecessary local variable assignment
- Addresses review feedback from Sourcery AI
* fix(config): increase default tool call timeout from 60 to 120 seconds
