Function TestVerboseLogCapturesTurnRecords

internal/tui/tui_test.go:701–754

TestVerboseLogCapturesTurnRecords drives a realistic two-round turn (reasoning → bash tool call → final answer) with logging on, and asserts the verbose records that make a session reconstructable for later debugging actually land in log.txt: the session header, the per-round request/packing summary
