Update coverage workflow to Python 3.10 and adjust numcodecs constraint

Align coverage workflow with test matrix baseline:

Coverage Workflow Changes:
- Change Python version from 3.12 to 3.10 for consistency
- Ensures coverage runs on same baseline as tests
- Reformatted YAML for consistency (auto-formatted)

Dependency Adjustment:
- numcodecs: >=0.15,<0.16 → >=0.13,<0.16 (broader stable range)
- Maintains NumPy 1.26.4 baseline compatibility

Rationale:
- Coverage must match test matrix baseline (Python 3.10)
- Prevents dependency resolution mismatches
- Ensures all CI workflows use stable ecosystem
