feat(scripts): kubera manga pipeline + print-on-demand
- kubera-sync.py: /r/kubera → Google Docs → CBZ manga translation
pipeline. Scans Reddit RSS, extracts translated images from linked
Google Docs, packages as CBZ. old.reddit.com endpoint (www.reddit.com
returns 429 from datacenter IPs). Idempotent, 6h systemd timer.
- aurelio-print.py: CBZ/PDF → tankobon booklet imposition → IPP submit
to CUPS print server. Saddle-stitch ordering, signature folding,
pure-Python PDF writer (no external deps). Targets CT244 print server.
