frostebite	c5355c5211	fix: replace orchestrator-develop branch references with main The orchestrator-develop branch no longer exists. Update all fallback clone commands and test fixtures to use main instead. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-09 20:03:29 +00:00
frostebite	70a78dab74	ci: set macOS builds to continue-on-error Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-05 23:33:25 +00:00
frostebite	5e54bcd4dd	fix(testing): use async exec for parallel test group execution Replace execSync with promisified exec so Promise.all actually runs test groups in parallel. Add native timeout support via exec options. Add 50MB maxBuffer for large Unity output. Fix ESLint violations (variable naming, padding lines, array push consolidation).
