Distill runtime/plugin extraction for al-folio v1.x.

• Distill layout renderer tag: {% al_folio_distill_render %}
• Distill templates/includes used by layout: distill
• Packaged Distill JS runtime under /assets/js/distillpub/*
• Packaged Distill stylesheet at /assets/css/al-folio-distill.css

Add the gem and plugin:

gem 'al_folio_distill'

plugins:
  - al_folio_distill
al_folio:
  features:
    distill:
      enabled: true

al_folio_core delegates layout: distill rendering to this plugin.

This gem ships prebuilt Distill runtime assets for end users (no npm step at gem install time).

• Source of truth: al-org-dev/distill-template (al-folio branch)
• Sync script: scripts/distill/sync_distill.sh
• Provenance metadata: assets/js/distillpub/provenance.json
• Runtime parity policy: vendored runtime hashes are pinned to match al-folio main snapshots carried by the upstream al-folio branch

Refresh vendored assets:

./scripts/distill/sync_distill.sh
# or pin a specific ref
./scripts/distill/sync_distill.sh <commit-sha>
