* fix: handle greetings without triggering research workflow (#733) * test: update tests for direct_response tool behavior * fix: address Copilot review comments for coordinator_node - Extract locale from direct_response tool_args - Fix import sorting (ruff I001) * fix: remove locale extraction from tool_args in direct_response Use locale from state instead of tool_args to avoid potential side effects. The locale is already properly passed from frontend via state. * fix: only fallback to planner when clarification is enabled In legacy mode (BRANCH 1), no tool calls should end the workflow gracefully instead of falling back to planner. This fixes the test_coordinator_node_no_tool_calls integration test. --------- Co-authored-by: Willem Jiang <willem.jiang@gmail.com>
