- Replaced the `setup` script in `package.json` with a call to `bun scripts/setup.ts`.
- Added `scripts/setup.ts` to run install, native build, coding-agent linking, and `link-omp` steps in order with step-level failure handling.
- Extended `scripts/bazel-natives.ts` with a `--cargo` flag, forbidding incompatible `--source`/bazel arg combinations, and using it to force local host backend selection.
