## Summary
- export the browser-safe `@fusion/core/column-roles` subpath
- keep Vite/Vitest aliases ahead of broad `@fusion/core` aliases
- restore production dashboard builds after task undo classification
adopted shared column-role helpers
## Test plan
- `node scripts/check-no-node-only-core-imports-in-dashboard.mjs`
- `FUSION_DASHBOARD_DEEP=1 pnpm --filter @fusion/dashboard exec vitest
run app/utils/__tests__/taskRevert.test.ts --pool=threads
--maxWorkers=1`
- `pnpm --filter @fusion/core typecheck`
- `pnpm --filter @fusion/dashboard typecheck`
- `CI=true pnpm check:changesets`
- `pnpm build`

## Summary by CodeRabbit
* **Bug Fixes**
* Fixed dashboard build compatibility for browser-based environments.
* Improved reliability when importing column role functionality across
supported application components.
* **Refactor**
* Made column role utilities available through a dedicated browser-safe
entry point.
* **Chores**
* Updated development and test configurations to consistently resolve
the new entry point.
* Documented the browser-safe module classification and recorded the
release patch.

The client bundle aliases `@fusion/core` to the leaf `core/src/types.ts` to
keep Node-only dependencies out of the browser, so a package-root import of
`FUSION_CLIENT_HEADER`/`FUSION_DASHBOARD_UI_CLIENT` typechecked but failed
`vite build`:
"FUSION_CLIENT_HEADER" is not exported by "../core/src/types.ts"
Follow the documented pattern instead of widening the root alias: declare a
`./task-delete-attribution` subpath export, add the matching Vite alias ahead
of the broader `@fusion/core` key (Vite matches in order), register the module
in the browser-safe-core allowlist, and import the subpath from the client.
`task-delete-attribution.ts` has no imports at all, so it is a safe leaf.
`app/utils/detectContentLanguage.ts` already warned about exactly this trap;
the miss was mine for verifying with typecheck, lint and test:gate but not
`pnpm build`, which is one of the four checks CI blocks on.
