perf: optimize test suite and CI pipeline for maximum speed
Test Suite Optimizations:
- Fix property-based test max_runs config (6s → 10ms, 99.9% faster)
- Replace Process.sleep with DateTime manipulation in timestamp tests
(5 tests × 1s → 10ms each, eliminating 5.5s of sleep time)
- Reduce agent channel test timeouts (1000ms → 800ms)
- Reuse fixtures in admin dashboard tests
- Result: Top 10 slowest tests reduced from 16.0s to 8.1s (50% faster)
CI Pipeline Optimizations:
- Restructure to compile-first architecture with artifact sharing
- Add parallel execution: quality checks (format + credo) run concurrently
- Enhance caching: Hex/Mix, Rust/Cargo, system deps, build artifacts
- Optimize dependency installation with conditional steps
- Improve PostgreSQL health checks and wait loops
- Result: 20-30% faster cold runs, 50-60% faster warm runs (estimated)
Architecture changes:
- Before: Single sequential job (format → compile → credo → test)
- After: Parallel pipeline (compile → [quality | test] → build)
Cache improvements:
- Add ~/.hex and ~/.mix caching
- Add Rust/Cargo target caching for Rustler NIF
- Include Rust source hashes in cache keys
- Skip apt-get update on cache hit
- Use --no-install-recommends for faster installs
