cleanup: remove deprecated Python artifacts + plan remaining items
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled

Deleted (11 files, 5 directories — not imported by any operational code):
  mcp/deploy/ (5 files) — old Python MCP deployment infra
  mcp/mcp-reader-shell — obsolete
  oikos/report.py — old Python scheduler reporter
  oikos/systemd/ (3 files) — old scheduler systemd units
  internal/.DS_Store — macOS artifact
  backups/ (2 SQL files) — old pre-cutover snapshots

Kept (operational, still needed):
  oikos/*.py (11 kernel files) — bin/homelab imports these
  oikos/cards/ (45 files) — 'homelab service explain'
  mcp/build_host_files.py — bin/homelab calls this
  ledger/ — bin/homelab writes change records
  hosts/ — generated from inventory
  secrets-issuance/ — standalone age-key service
  ssh/, tools/, vps/ — operational scripts
  bin/homelab — active Python CLI (not fully ported)

Remaining plan:
  1. Port bin/homelab fully to Go (most remaining subcommands)
  2. Delete oikos/*.py + mcp/build_host_files.py after port
  3. Infisical bootstrap (needs image pull)
  4. Gitea webhook cleanup (ids 10, 11)
  5. Watchdog manual test + rollback formal drill

"""oikos/report.py — daily morning brief + weekly operator report.
Both are generated text, not sent directly to Matrix — same integration
contract as oikos/approve.py: there's no dedicated Matrix bot in this
homelab, so Hermes (already posting alerts as @dtoro:avispero, see
knowledge/wiki/infrastructure/monitoring.md) is the one that actually delivers this text.
The daily brief is meant to run once a day (e.g. chained after an early
oikos-scheduler.service run, or its own systemd timer); the weekly report
is a deeper markdown review.
Both are grounded only in what's actually implemented: signal state,
pending approvals, and change-ledger history. There's no Prometheus yet
(Week-3 backlog item pending LXC provisioning), so there are no trend
lines here — only point-in-time counts.
