[/tdd] The regression test covers the happy path (command present on tool.execution_start), but misses the merge case: when both data.input (or data.parameters) and data.command are present and base.command is undefined. Adding a test for that branch would prevent a silent regression if the merge logic changes.

💡 Suggested additional test

    '{"type":"assistant.message","data":{"content":"Done"}}',

  const result = parseCopilotLog(eventsLog);
  expect(result.markdown).toContain('ls');
  expect(result.markdown).toContain('/tmp'); // cwd from input preserved
});

@copilot please address this.

Addressed in 1538d63. Added regression coverage for the merge path where structured input is preserved and data.command is merged in when input.command is absent.
