neon 992224f2e8 feat(books): add read-aloud generation
Generate a synced read-aloud EPUB from a book's EPUB and audiobook through an
optional STAlign worker (Docker on CPU, or native with MLX on Apple Silicon),
with review, re-sync, replace in place, restart recovery and live progress on
the Files tab. Book details also stack the ebook and audiobook covers when
both exist. See docs/READ_ALOUD.md.

# Put this inside the same mount as your download client's completed directory. A finished
# download is hardlinked into the dock so the torrent keeps seeding from the same bytes, and two
# separate bind mounts of one filesystem still refuse the link even though they report the same
# device: under Docker or Kubernetes that means every fulfilment silently copies and uses the
# space twice. Linux fs.protected_hardlinks=1 also requires the BookOrbit process user to own the
# completed source file or be able to write it. Run BookOrbit and the download client with the same
# UID, or use a shared group that grants BookOrbit write access to completed files. The per-mapping
# test under Settings > System > Requests creates a BookOrbit-owned file, so it validates the mount
# and paths but cannot prove that a differently-owned completed file is linkable.
