S3 + CloudFront Directory Indexer — 2026-06-30_v018

Browser-only hotfix/polish release.

Changes from v017:
- Fixed client-side safe query parsing so live TOOLS and live sorting work again.
- Restored Type to the client-side sortable column list.
- Restored client-side size-unit state.
- TOOLS stays open when using tool links.
- Side margins changed to 12px; top margin remains calm.
- Right-column gaps changed to 12px.
- Image/art icon changed to 🎨.
- Long filenames get a separate touch-safe ⋯ button that opens a readable filename popover without navigating.
- The popover includes an Open link for deliberate navigation.
- Normal short filenames do not get extra visual noise.
