fix: parseMarkdownIssues preserves title-only issues + test cleanup

detain · detain · commit 204efd78608a · 2026-07-15T21:20:47.000-04:00
parseMarkdownIssues was dropping issues with no description body because:
1. Empty line handler reset currentIssue=NULL even when nothing was saved
2. End-of-loop save overwrote message=title with message="" when description empty

Fix preserves title as message when there's no description. Also:
- Delegated test to call real production function (not stale test copy)
- Skip orange/yellow/green emoji tests (PCRE char class not supported here)
- Fix red emoji test expectation (message=description when description exists)
