Move all [script("bun")] blocks into standalone TypeScript files under
scripts/ with shared utilities in scripts/lib/. The Justfile is now ~40
lines of thin `bun scripts/*.ts` wrappers.
Shared code consolidated into two lib files:
- lib/proc.ts: process spawning (run, spawnCollect, raceInOrder, ProcessGroup)
- lib/fmt.ts: color output, elapsed timers, reusable flag parser
Add logic to detect and label asynchronous online sections (INT building
with TBA times) separately from synchronous online courses. Update table
rendering to show "Async" instead of "TBA" for these sections.
Reorganize CI pipeline into separate jobs for Rust quality, frontend
quality, tests, Docker build, and security audits. Add cargo-audit,
bun audit, and Trivy filesystem scanning. Allow formatting checks to
pass with warnings on push events while failing on PRs.
