- Vendor TRE regex library (BSD-licensed, ~9K LOC) for Windows —
eliminates the TODO stub that caused all regex tests to fail
- Fix cbm_mkdtemp stack-buffer-overflow: use static buffer for
/tmp/ → %TEMP%\ path translation (Windows paths are longer)
- Wine test results: 1861 passed, 50 failed (Wine filesystem limits),
75 skipped — remaining failures are Wine-specific, not Windows bugs
