Add two new benchmark variations to the task runner system: - build: install deps, then time `<pm> run build` (cold build, no .next/ cache) - build-cache: install deps + run build once to warm .next/ cache, then time `<pm> run build` again (cached rebuild) Changes: - Add scripts/variations/build.sh and build-cache.sh following run.sh patterns - Add clean_build_output helper to clean-helpers.sh (removes .next/ directory) - Register build/build-cache as available variations in bench CLI - Allow nx/turbo/vp/node package managers for build variations (task runners) - Add build/build-cache to CI workflow matrix (targeting next fixture) - Update generate-chart.js to process build/build-cache result files - Update process-results.sh to copy build/build-cache artifacts - Add build/build-cache to app Variation type, validation, sort order, and task execution category - Default task-runners route now navigates to build instead of run Co-authored-by: Darcy Clarke <darcy@darcyclarke.me>
The warm build step in the prepare phase can fail for some package managers (e.g. vlt). Since hyperfine aborts on non-zero prepare exit codes, add || true to all install and warm build commands in the build-cache prepare steps to let --ignore-failure handle it.

Summary
Add two new benchmark variations to the task runner system:
build: Install deps, then time<pm> run build(cold build, no.next/cache)build-cache: Install deps + run build once to warm.next/cache, then time<pm> run buildagain (cached rebuild)These measure framework build performance across package managers and task runners (npm, yarn, pnpm, vlt, bun, deno, nx, turbo, node, etc.).
