chore: parallelize checks, frontend builds, and unit tests

- check.sh: run npm check, deps:check, and rust-lint-format.sh in
  parallel after npm ci + build (biggest win — Rust compilation no
  longer blocks JS checks)
- validate-and-test-all.sh: build all 3 frontend assets in parallel
- run-test.sh: run 4 JS vitest workspaces in parallel (acceptance
  tests remain sequential as they use PocketIC)
