Fixes

1. Fixed shard calculation in RemoteWrite. Previously the number of shards could exceed the required amount.
2. Encoder version check when restoring the last head. If the WAL file encoder version differs from the current one, that WAL is considered impossible to continue and the head is rotated to create an up-to-date WAL.
3. Fixed data race causing service crashes. A mutex was added to linearize tasks when loading evicted series into memory across multiple shards, preventing race conditions.
4. Skipped empty labels in OTLP Protobuf message processing. Empty labels are now ignored during processing.
5. Fixed shard count change application. On-the-fly shard count changes now trigger forced rotation immediately, instead of waiting for the next scheduled rotation.
6. Renamed TSDB state metrics. Metrics have been renamed to align with standard vanilla Prometheus metrics.

Enhancements

1. Optimized allocations of cross-shard objects. Objects are now allocated and freed together in contiguous memory.
2. Optimized concurrent execution of recording rules. Rules that do not depend on other rules in the group append data into a single shared batch which is added to the head once. This significantly speeds up recording rules.
3. Reduced allocations in instant queries. The number of allocations in instant queries, commonly used in the federate API, has been significantly reduced.
4. Optimized sample decoding. Removed intermediate in-memory sample storage and double-copying during decoding.
5. Removed unused code. This reduces the final binary size.
6. Minor optimizations. Various small improvements have been made to enhance overall performance.
