Function TestParseEventsJSONLFile

pkg/cli/copilot_events_jsonl_test.go:85–184

TestParseEventsJSONLFile verifies that parseEventsJSONLMetrics correctly extracts turns, tool calls, tool sequences, and token counts from events.jsonl using the real Copilot CLI format (nested data object, tool.execution_start events).
