Prepare the repository for a public release

- docs/deployment.md: step-by-step Docker deployment for anyone (setup,
  configuration, LAN/HTTPS/VPN access, adding manga, operation, prebuilt
  images, backups, peering, troubleshooting, rules for agents).
- deploy/circus.sh: host helper without Node (status, up/down with queue
  pause, logs, pause/resume, update, rescan, restore-test); deploy/compose.https.yml
  + Caddyfile for automatic HTTPS.
- README rewritten for public readers (Docker first, sources/copyright note,
  docs index); AGENTS.md + CLAUDE.md for contributors and coding agents.
- Removed notes about one particular installation (Windows host, handoffs,
  audits of a private library, benchmarks with local paths, wishlist, reading
  map) and the unused ops/proxmox templates; generalized remaining mentions of
  hosts, VPN and Windows-only commands.
- Defaults: TZ and reading time zone UTC; .gitattributes keeps shell/YAML LF.
- Personal agent coordination files are git-ignored (CLAUDE.local.md,
  .claude/skills/manga-org/).

 The exact file split is a proposal, not a requirement to create empty modules. Start with storage and identity tests, then the deterministic pipeline, then API/UI. Do not add model-provider plumbing, a new Compose service, or a nightly timer in the first implementation slice. A candidate must pass schema validation and duplicate/identity checks before it can appear in a published feed.
