v0.50.3

Highlights

• Project admission is now versioned independently from repository resources, including projects without repositories and multiple repositories per project.
• Existing daemon configuration migrates while preserving repository credentials and stable project identifiers.
• Kit packages can be installed as verified immutable artifacts and commands resolve by qualified owner.
• Runtime calls emit correlated per-call spans, and workers can receive read-only sibling context repositories.

Release engineering

• Local release snapshots now skip the production signing pipe explicitly; tag-pushed releases continue to use signing and notarization.
