Tranche 7 — all 11 raw sites in sleeper.go. Adds sleep_enabled and
sleep_idle_minutes to schema.sql and three runtime.sql queries:
ListSleepCandidates, GetServiceDomainText, GetServiceStatusText. Status
writes reuse SetServiceStatus; the wake loader reuses
GetServiceRuntimeWithOwner (the projects join is FK-safe).
Also drops a dead port read in handleServiceSleep that was loaded but
never used.
TestRuntimeLiveInvariants now covers the sweep filter and both text
lookups on live Postgres.

- Wake placeholder fired its wake callback unconditionally at boot, so
sleeping services flapped sleep→wake on every idle timeout. The wake
call now lives in a CGI script the busybox httpd runs on inbound hits;
E404 covers non-root paths. URLs/page travel via env, no quoting.
- Wake endpoint tries ordered candidate addresses (self-name on shared
net, host.docker.internal, edge gateway, probe) — Docker Desktop's VM
can't reach the bridge gateway, so single-URL wake was dead there.
- CreateServiceRequest accepts sleep_enabled/sleep_idle_minutes and the
INSERT persists them — previously update-only, silently dropped at
create. CLI `services create` gains --sleep/--sleep-idle; MCP doc lists
both; OpenAPI node_id description updated for build-on-node.
- Wake goroutine logs spec/reconcile failures instead of a bare return,
and marks the service failed when spec build errors.
- scripts/build-cli.sh ships containr-agent-linux-{amd64,arm64} so the
install-agent.sh GH-releases fallback actually resolves.
Verified live: create-time flags persist and validate (1-1440), service
sleeps on idle and stays asleep, an inbound hit on the placeholder wakes
it (~15s to running), and the placeholder is pruned after reconcile.

Agents report per-container net IO at heartbeat; the sleeper measures
idleness from those counters for remote services, removes replicas via
the agent queue, and repoints the domain route at the backend's new
/internal/wake-page endpoint (replacePath + priority-100 route in the
file provider). First hit serves a reloading page and retriggers the
wake reconcile, which recreates replicas and restores real upstreams.
Manual POST /services/:id/sleep also routes remote; local sleep/wake
flow is unchanged.

Services gain sleep_enabled + sleep_idle_minutes. A 30s sweeper tracks
container NetworkIO deltas; a flat counter for the configured window
scales the service to zero (status=sleeping, workload containers removed).
While slept, a busybox wake container takes over the service's Traefik
host rule at priority 100: it serves a self-reloading "waking" page and
calls the unauthenticated idempotent GET/POST /api/v1/internal/wake/:id,
which reconciles the service back to running. Wake placeholders carry a
dedicated label (containr.wake-for) so runtime state never counts them;
the sweeper prunes them once the workload is up. The wake URL resolves
the API via its container name when containerized, else the edge
network's IPAM gateway — bare-metal installs need HOST=0.0.0.0 for the
callback.
Surfaces: PUT fields on services, POST /services/:id/sleep|wake,
CLI --sleep/--sleep-idle + services sleep|wake, 2 MCP tools (89 total),
OpenAPI paths/schema, and a Settings > Sleep card with toggle, idle
minutes, and manual sleep/wake plus a Sleeping badge.
Verified live: idle sweep scaled whoami-web to zero; the wake container
served the page on the edge network and its callback woke the service
(container recreated, status running, placeholder pruned).
