skeleton: package, schema, config, CLI, alembic, CI, deploy, docs

- cayceops core: env-only config (CAYCE_OPS_*), engine/session, ORM models
  with state machines (proposal/mail/content) and audited writes
- provider-agnostic LLM interface (null provider default, stdlib openai-compat)
- Typer CLI with lazy component loading (scanner/executor/maild/publisher/monitor)
- alembic 0001 initial schema; sqlite-portable JSON columns
- tests: 7 passing on throwaway sqlite; fixtures invented, never real data
- ci: ruff + alembic smoke + pytest + gitleaks(full history) in
  .gitea/workflows + .github/workflows; local gate = make check
- deploy: docker-compose (postgres 16) + hardened systemd units/timers
- docs: DECISIONS D1-D9; README project (grant text retired)
