What's in this release
Stop "no such table: book_format_checksums" log spam when KOReader sync is disabled (#94, fixes upstream CWA #1183 — reporter @Bugg6).
If you upload books or save metadata changes on an instance that's never enabled KOReader sync, the logs were filling with errors like:
[cover-metadata-enforcer] Warning: Failed to store checksum for book 2
ERROR Failed to store checksum for book 2: no such table: book_format_checksums
Root cause: cps/helper.py called the checksum write on every metadata embed, regardless of whether KOReader sync was on. Without sync, the book_format_checksums table is never created, so every write failed.
Fix: gate the call on is_koreader_sync_enabled() — same gate other parts of the code already use. The pure utility function stays unguarded so explicit-backfill paths (used right after a user enables sync) still work. 3 regression tests pin the gate.
