Summary by cubic

Regenerates the repository from the fixed template: shellcheck compliance for the bin/mise bootstrap script and authenticated GitHub Actions docs jobs.

• Fixes shellcheck violations (SC2250, SC2088, SC2249, SC2312, SC2269) in bin/mise and guards command substitutions with || true so failures don't abort under set -e.
• Docs workflow now passes GITHUB_TOKEN and MISE_GITHUB_TOKEN to avoid unauthenticated API rate limits and removes the explicit Pages environment block.
