* fix: resolve lint and type errors to enable CI - Remove stale biome-ignore suppressions in bootstrap.ts, r3f.d.ts, and parametric-node-renderer.tsx (rules no longer fire). - Replace forEach callbacks that return values with for...of loops in node-actions.ts and build-collider-world.ts (lint/suspicious/useIterableCallbackReturn). - Rewrite assign-in-expression guards in ceiling/tool.tsx to explicit if-statements (lint/suspicious/noAssignInExpressions). - Hoist useMemo/useCallback above early return in chimney/panel.tsx (lint/correctness/useHookAtTopLevel). - Add `^build` to turbo check-types dependsOn so packages/core dist is up-to-date before type checking — this resolves all 32 type errors which were caused by stale dist, not missing symbols. * ci: add lint and typecheck workflow on push/PR Adds a quality gate that runs `bun run check` (Biome) and `bun run check-types` (TypeScript) on every push and PR to main. Uses concurrency groups to cancel stale runs. Closes #147. --------- Co-authored-by: Pascal <open@pascal.app>
