5a377a2198 PDF reading via pdf.js
- PdfReader renders PDFs to canvas with page navigation and page-number
  progress, reusing the same integer progress model as comics.
- Reader routes by file container, not media kind, so a PDF in a comics
  library and a PDF ebook both open in the PDF reader.
- pdf.js is dynamically imported: the main bundle stays 443 kB and the 474 kB
  pdf chunk plus 1.26 MB worker load only when a PDF is actually opened.
- comics cover extractor now only handles zip archives. A PDF in a comics
  library is a valid item but not a zip, so it returns no cover instead of
  logging an error on every request.
- fixed the page scale to leave slack for the vertical scrollbar, which was
  otherwise forcing a horizontal scrollbar on tall pages.

Verified live: a 3-page PDF renders, navigates, and reports 33% progress.

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.

c3b7db7114 Phase 4: CBZ comics module and reader
- comics: reads pages straight out of the archive on demand. No extraction
  pass, so a 200-page CBZ is not materialised for a reader who views three
  pages. Pages are read into memory and served via http.ServeContent, which
  gives Range for free.
- natural page ordering: page2 sorts before page10. Lexical ordering shuffles
  a numbered archive, which is the difference between a readable book and a
  scrambled one.
- skips __MACOSX and dotfiles; rejects archives with no images.
- cover is the first page.
- media.Item gained ModTime (from the backing file) so page responses carry a
  Last-Modified and support conditional GETs.
- web: ComicReader with a bounded prefetch window (two pages each way), page
  jump, keyboard nav, and progress stored as a page number.

Verified: 3-page CBZ served in natural order, out-of-range 404, cover from
page 1, progress round-trip. svelte-check 0/0.
