Hongming Wang 3a6d2f179d feat(ops): add sweep-cf-tunnels janitor — orphan Cloudflare Tunnels accumulate
CP's tenant-delete cascade removes the DNS record (with sweep-cf-orphans
as a backstop) but does NOT delete the underlying Cloudflare Tunnel.
Each E2E provision creates one Tunnel named `tenant-<slug>`; without
cleanup these accumulate indefinitely on the account, consuming the
tunnel quota and cluttering the dashboard.

Observed 2026-04-30: dozens of `tenant-e2e-canvas-*` tunnels in Down
state with zero replicas, weeks past their tenant's deletion. Same
class of bug as the DNS-records leak that drove sweep-cf-orphans
(controlplane#239).

Parallel-shape to sweep-cf-orphans:
  - Same dry-run-by-default + --execute pattern
  - Same MAX_DELETE_PCT safety gate (default 90% — higher than DNS
    sweep's 50% because tenant-shaped tunnels are orphans by design)
  - Same schedule/dispatch hardening (hard-fail on missing secrets
    when scheduled, soft-skip when dispatched)
  - Cron offset to :45 to avoid CF API bursts colliding with the DNS
    sweep at :15

Decision rules (in order):
  1. Name doesn't match `tenant-<slug>` → keep (unknown — never sweep
     tunnels that might belong to platform infra).
  2. Tunnel has active connections (status=healthy or non-empty
     connections array) → keep (defense-in-depth: don't kill a live
     tunnel even if CP forgot the org).
  3. Slug ∈ {prod_slugs ∪ staging_slugs} → keep.
  4. Otherwise → delete (orphan).

Verified by:
  - shell syntax check (bash -n)
  - YAML lint
  - Decide-logic offline smoke (7 cases, all pass)
  - End-to-end dry-run smoke with stubbed CP + CF APIs

Required secrets (added to existing org-secrets):
  CF_API_TOKEN          must include account:cloudflare_tunnel:edit
                        scope (separate from zone:dns:edit used by
                        sweep-cf-orphans — same token if scope is
                        broad, or a new token if narrowly scoped).
  CF_ACCOUNT_ID         account that owns the tunnels (visible in
                        dash.cloudflare.com URL path).
  CP_PROD_ADMIN_TOKEN   reused from sweep-cf-orphans.
  CP_STAGING_ADMIN_TOKEN reused from sweep-cf-orphans.

Note: CP-side root cause (tenant-delete should cascade to tunnel
delete) is in molecule-controlplane and worth fixing separately. This
janitor is the operational backstop in the meantime — same pattern
applied to DNS records when the same root cause was unaddressed.
