fix: Include packageName in resolution digest calculation

Critical bug fix: packageName was missing from the digest calculation.
Changing packageName from "prometheus" to "grafana" would incorrectly
reuse the rolling-out revision if other fields (version, channels, etc.)
remained the same.

Changes:
- Add PackageName field to resolutionInputs struct
- Include catalog.PackageName when building the digest
- Update label comment to document packageName is hashed

Verification:
- Changing packageName now produces different digests
- All tests pass
