Commit Message

fix materializer recovery for empty log descriptors (#76)

## Summary

- Treat empty log descriptors as runtime-routed logs when recovery
unlocks shard materializers.
- Keep legacy tag-filtered descriptors scoped to the matching shard.
- Add a fresh-cluster regression for Bedrock 0.5-style empty log
descriptors.

## Root Cause

Fresh Bedrock 0.5 layouts use empty log descriptors because shard-to-log
routing is computed at runtime. Recovery still filtered materializer
unlock logs by shard tag, so `[]` matched no shard and each
fresh-cluster materializer started with no logs to pull from.
