Extracted from the now-closed PR #1664 (Molecule-AI/molecule-core). - New scripts/molecule-gh-token-refresh.sh background daemon — every 45 min (TOKEN_REFRESH_INTERVAL_SEC) calls the credential helper's _refresh_gh action to keep both gh CLI auth and the on-disk cache fresh through the GitHub App installation token's ~60 min TTL. - scripts/molecule-git-token-helper.sh rewritten with a ~50 min on-disk cache (${CACHE_DIR}/gh_installation_token + _expiry companion file), a cache > API > env-var fallback chain, a new _refresh_gh action (invoked by the daemon above), a _invalidate_cache action, and path references flipped from /workspace/scripts/... to /app/scripts/... to match the runtime image layout. - Dockerfile copies the new refresh daemon and extends mkdir to create /home/agent/.molecule-token-cache at build time. - entrypoint.sh configures the git credential helper for github.com while still root (so the global gitconfig is written before the gosu handoff), creates + chowns the token cache dir, then as agent starts the refresh daemon in the background and does an initial gh auth login from GITHUB_TOKEN/GH_TOKEN so gh works before the first refresh fires. Dropped from PR #1664: cosmetic em-dash -> ASCII hyphen rewrites (charset-normalizer noise) that would conflict with the repo's existing em-dash convention used elsewhere in workspace/.
