ci: add lint and typecheck workflow (closes #147) (#369)

* 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.
