feat(deploy): Complete mini-PaaS deployment system (t-266)

- Add Omni/Deploy/ with Manifest, Deployer, Systemd, Caddy modules
- Manifest CLI: show, update, add-service, list, rollback commands
- Deployer: polls S3 manifest, pulls closures, manages systemd units
- Caddy integration for dynamic reverse proxy routes
- bild: auto-cache to S3, outputs STORE_PATH for push.sh
- push.sh: supports both NixOS and service deploys
- Biz.nix: simplified to base OS + deployer only
- Services (podcastitlater-web/worker) now deployer-managed
- Documentation: README.md with operations guide
