Fixes queued snapshot builds for multi-dimensional Neos sites.
- Enqueues fulltext roots for every allowed content-dimension combination.
- Preserves the explicit target dimension through worker execution, including fallback and shine-through hashes.
- Keeps existing live-publish job defaults compatible.
- Adds regression coverage for Romanian and fallback dimension behavior.
After upgrading, rebuild with ./flow nodeindexqueue:build --verbose and let the worker drain the queue.
