Improve query planning performance by reducing string allocation and cloning in the batch fetch optimization. This change applies `FastStr` in internal optimizer paths used to build batched entity fetches, which significantly improves query-plan benchmark throughput while preserving planner behavior.

Code Review
This pull request effectively improves query planning performance by replacing String with the interned FastStr type in the batch fetch optimization path, reducing string allocations. The changes are well-contained and focused. I've added a couple of suggestions to further reduce allocations during the conversion from String to FastStr, which will make this optimization even more effective.
