0212d089ec Phase 6c: photo thumbnails and viewer
- photos: generates a downscaled JPEG thumbnail per image, because serving a
  folder of 12-megapixel originals to a grid is unusable on a TV box. Uses
  CatmullRom scaling via golang.org/x/image; decodes jpeg/png/gif/webp.
- an undecodable format returns no thumbnail rather than an error, so the grid
  falls back to a placeholder.
- images already smaller than the 512px ceiling are passed through untouched.
- library items endpoint now returns library_id, which the viewer needs to
  find its siblings for navigation.
- web: PhotoViewer with keyboard and button navigation within the library.

Verified: 900x1200 PNG thumbnailed to a 512-long-edge JPEG and served;
unit tests assert exact dimensions, aspect preservation, and that non-images
produce no thumbnail without erroring.

1b11867efe Phase 6a: directory grouping, audiobooks and music playback
A book is a folder of chapters, not a file. The scanner gained a grouping
mode so a directory of tracks becomes one item with ordered files.

- registry: MediaType.Group (file | directory). Audiobooks and music group by
  directory; everything else stays one item per file.
- scanner: builds groups, upserts one item per group, marks items missing when
  their directory disappears, and keeps the file-level added/updated/missing
  accounting. Tracks are ordered naturally, so chapter 2 precedes chapter 10.
- natsort: one shared natural-order comparator, now used by both the scanner
  and the comics module (which had its own copy).
- media: GET /items/{id}/files/{fileID} streams one specific track. It
  verifies the file belongs to the item, so an item id cannot be paired with
  another item's file id.

No new module was needed for playback: the polymorphic progress table already
keys on file_id, so per-chapter resume fell out of the existing design. The
web player resumes the exact track and offset.

Verified: 3 chapters grouped into one book titled "Mistborn", natural order,
range request returned 206, mismatched file id 404s, per-track progress
round-trips.

5458b0a28a Phase 2: libraries and the file scanner
- library: CRUD with root-path resolution (absolute, symlink-free, must be
  readable). A library name is unique; the root is validated at creation.
- registry: media types declare their extensions; the core never imports a
  module. RegisterType is the extension point.
- scanner: walks a root, reconciles media_items/media_files in one
  transaction, skips unchanged files by size+mtime, and marks vanished files
  missing rather than deleting them (progress is the one thing here that
  cannot be regenerated). A single unreadable file never fails a scan.
- migration 0002: `missing` flags on items and files, plus indexes.
- endpoints: media-types, library list/get/create/delete, per-library items,
  and scan. Library reads go through the same grant chokepoint as everything
  else; an unauthorised library 404s rather than 403s so its existence is not
  leaked.
