Fix build system issues: vitest alignment, tsconfig paths, CI actions, yarn build

- Align bugc vitest/coverage/ui versions from ^2.1.8 to ^3.2.4 to
  match all other packages and root; update deprecated `threads: false`
  to `pool: "forks"` for vitest 3 compatibility
- Add missing tsconfig paths for #evmgen/program-builder and
  #irgen/debug/variables in bugc (were in package.json imports but
  missing from tsconfig, breaking IDE resolution)
- Fix `yarn build` to generate schema yamls.ts before tsc, so it
  works on fresh clones without a prior `yarn install`
- Update GitHub Actions from v3 to v4 across all CI workflows
  (checkout and setup-node)
