test: add missing coverage for cmdLast (#1176)
Added comprehensive test suite for cmdLast function (PR #1171 feature). Covers: - Empty history (no records) - History with records (rerunning latest) - Record hints and prompt display - Helper functions (buildRecordLabel, buildRecordHint) - Edge cases (old timestamps, metadata fields, selection logic) Tests increased from 13,685 to 13,712 (+27 tests). Agent: test-engineer Co-authored-by: spawn-refactor-bot <refactor@openrouter.ai> Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>

/**
|

* Tests for cmdLast — the feature added in PR #1171 that reruns the most recent spawn.
|
||||
*
|
||||
* cmdLast() reads history, finds the newest record, and calls cmdRun to rerun it.
|
||||
* This integration test covers:
|
||||
* - Empty history (no records)
|
||||
* - History with records (reruns most recent)
|
||||
* - Manifest available (uses display names)
|
||||
* - Manifest unavailable (falls back to raw keys)
|
||||
* - Records with/without prompts
|
||||
* - Integration with cmdRun (mocked)
|
||||
*

||||
* Agent: test-engineer
