Fix Quay GitHub SSH submodule auth

[lafawnduh1966]

Summary

• install a Quay-scoped Git include for GitHub App auth so Quay worktrees rewrite SSH-shaped GitHub URLs to HTTPS
• persist the same helper + rewrites on app-auth code mirrors and bare repos
• extend setup verify to catch missing Quay App gitconfig/includes and clone-local auth drift

Validation

• bash -n installer/setup-hermes.sh
• python -m py_compile installer/hermes_installer/verify.py tests/ops/test_setup_hermes_verify.py
• git diff --check
• scripts/run_tests.sh tests/ops/test_setup_hermes_verify.py
• hotfixed krustentier and verified git ls-remote git@github.com:InverterNetwork/iTRY-frontends.git HEAD succeeds from a Quay worktree path
• validated linked-worktree gitdir pattern under /home/hermes/.hermes/quay/repos/.git/worktrees/ loads the scoped include
