* feat/change-tsid-gen:
perf(metric-engine): replace mur3 with fxhash for faster TSID generation
- Switches from mur3::Hasher128 to fxhash::FxHasher for TSID hashing
- Pre-computes label-name hash when no nulls are present, avoiding redundant work
- Adds fast-path for rows without nulls; falls back to slow path otherwise
- Updates Cargo.toml and lockfile to reflect dependency change

* feat/change-tsid-gen:
fix: only check primary-key labels for null when re-using cached hash
- Rename has_null() → has_null_labels() and restrict the check to the
primary-key columns so that non-label NULLs do not force a full
TSID re-computation.
- Update expected hashes in tests to match the new logic.

* feat/change-tsid-gen:
bench: add criterion benchmark for TSID generator
- Compare original mur3 vs current fxhash fast/slow paths
- Test 2, 5, 10 label sets plus null-value slow path
- Add mur3 & criterion dev-deps; register bench target

* feat/change-tsid-gen:
test: stabilize metric-engine tests by fixing non-deterministic row order
- Add ORDER BY to SELECTs in TTL tests to ensure consistent output
- Update expected __tsid values after hash function change
- Swap expected OTLP metric rows to match new ordering
