Subject: [PATCH] Fix case-insensitive remote URL matching for GitHub PRs

Normalizes the repository owner to lowercase during the PR
mapping.
This ensures that PR icons and integration features work correctly even
when the local git remote URL casing differs from the official
repository casing on GitHub.
