Walkthrough

Adds a “Normalize GHCR repository” step in two jobs of .github/workflows/docker-image-arm64.yml to compute and export GHCR_REPOSITORY by lowercasing GITHUB_REPOSITORY, positioned after tag resolution/extraction. No other logic changes.

Poem

I hopped through YAML fields at night,
Lowercasing names by moonlit byte.
GHCR now knows where to go,
Tags resolved, the images flow.
With gentle paws, I press “commit” —
A tidy warren, workflows fit. 🐇🚀
