[Fix] Fast widgets fail during BullMQ-resumed turns

​Opened on behalf of @daniel-lxs. Follow up by mentioning @roomote-roomote, in the web UI, or in Telegram.

What changed

• Emit JSDOM's synchronous XHR helper beside the bundled BullMQ entrypoint so Fast show_widget sanitization can resolve it during resumed turns.
• Declare JSDOM directly in the BullMQ package so its build configuration resolves only dependencies owned by that workspace.
• Add a real built-artifact regression test that runs the BullMQ tsup configuration and verifies the helper resolves from the generated bundle location.
• Fail the final application image build if the helper does not reach the BullMQ runtime directory.

Why this change was made

JSDOM retains a runtime require.resolve("./xhr-sync-worker.js") inside the bundled BullMQ entrypoint. BullMQ previously emitted only dist/index.js, so Fast turns resumed by BullMQ failed when show_widget initialized the sanitizer even though API-owned Fast turns had the complete external JSDOM package available.

Impact

Fast widgets can render during BullMQ-resumed turns without a missing-module failure. The fix does not change widget sanitization or UI behavior; it restores the required runtime asset and adds build-time coverage. The build also works from BullMQ's declared dependency boundary rather than relying on root installation layout. All BullMQ tests and repository pre-push checks pass. Full Docker image assembly was not available in the task sandbox because it has no Docker daemon, so the final-stage file assertion will run when CI builds the image.

No new code issues found. See task

• apps/bullmq/tsup.config.ts:7 resolves jsdom without declaring it as a BullMQ dependency, causing the build config to fail under pnpm's package layout.

Resolved the missing direct BullMQ dependency in 5be3ee68. @roomote/bullmq now declares the exact JSDOM version used by its build config; frozen install, production build, artifact tests, typecheck, and pre-push checks pass.
