f9e34fd0c6 refactor(install): route orchestrator-managed apps through orchestrator first
Phase 3a of the install path consolidation. Two coupled changes:

1. install.rs handle_package_install: gate the legacy "container exists →
   adopt + return" probe on !orchestrator_managed. Apps the orchestrator
   knows about (bitcoin-knots, bitcoin-core, lnd, electrumx, fedimint,
   filebrowser, btcpay-server stack apps, mempool stack apps, plus the
   companion UIs that just moved to Quadlet) skip the legacy probe and
   fall straight into the orchestrator branch.

   The legacy adopt block was returning success on a bare `podman start`
   exit-0 — even when the process inside the container crashed seconds
   later. That's the .228 "running but unreachable" failure mode. The
   orchestrator's ensure_running honors the manifest's health check and
   pre-start hooks (e.g. re-renders bitcoin-ui's nginx.conf if the RPC
   password rotated), so this is a behavioral upgrade, not just a
   refactor.

2. ProdContainerOrchestrator::install: make idempotent. Previously it
   blindly called install_fresh which would fail on `podman create` if
   the container name already existed. Now it delegates to ensure_running:
     - Container Running + healthy → no-op (refresh hooks, restart if
       config rewritten)
     - Container Stopped/Exited → start (with hook refresh)
     - Container missing → install_fresh
     - Container in wedged state (Created/Paused/Unknown) → force-recreate

   Without this, change #1 would regress every "container already exists"
   case for the 18 orchestrator-managed app IDs. With it, install becomes
   the single source of truth for "make app X be in the desired state."

Tests: 654 passed across the workspace (614 unit + 37 orchestration + 3
rpc), 0 failures. The 20 prod_orchestrator tests cover the install /
ensure_running / reconcile paths the new install delegates through.

Net delta: install.rs grows by ~30 lines (gating wrapper + comments),
prod_orchestrator.rs grows by ~30 lines (idempotent install body). Both
are temporary — the larger deletions (~1700 lines) come once every app
has been verified through the orchestrator path in subsequent phases.

23c4e7441f refactor(container): move companion UIs to systemd via Quadlet
Companion UI containers (archy-bitcoin-ui, archy-lnd-ui,
archy-electrs-ui) used to be launched as fire-and-forget tokio::spawn
blocks from install.rs. If archipelago crashed mid-spawn or the
container's cgroup was reaped, companions vanished from podman ps -a
and only a manual rm/run could bring them back (the .228 incident).

Now each companion is rendered as a Quadlet .container unit under
~/.config/containers/systemd/, daemon-reloaded, and started via
systemctl --user. systemd owns supervision from that point on:

- archipelago can crash, restart, or be uninstalled without touching
  any companion.
- Quadlet's Restart=always + RestartSec=10 handles container exits.
- A 30s reconcile tick in boot_reconciler enumerates expected
  companion units and re-installs any whose unit file or service
  vanished — defense-in-depth against external tampering.

New module layout:
- container/quadlet.rs: pure unit renderer + atomic write_if_changed
  + systemctl helpers (daemon_reload_user / enable_now / disable_remove
  / is_active). 6 unit tests, no I/O in the renderer.
- container/companion.rs: per-app companion specs, install/remove/
  reconcile, image presence (build local first, fall back to insecure
  registry only via image_uses_insecure_registry whitelist). 2 tests.

install.rs handle_package_install now ends with a single call to
companion::install_for(package_id), replacing 287 lines of spawn-and-
hope shellouts plus a ~120-line nginx auth-injector helper that worked
around per-node RPC password baking. The helper is gone too — the
pre-start hook renders the per-node nginx.conf to /var/lib/archipelago/
bitcoin-ui/nginx.conf and the Quadlet unit bind-mounts it read-only.

runtime.rs handle_package_uninstall now disables companions before
the container rm loop. Otherwise systemd's Restart=always would
respawn each companion within ~10s of removal.

Tests: 53 container tests pass, including 6 quadlet renderer tests
(host network, bridge network, capability set, atomic write idempotence)
and 2 companion specs (per-app companion lookup, build_unit shape).
boot_reconciler tests gain a #[cfg(test)] without_companion_stage()
flag so the paused-clock fixtures don't race the real systemctl I/O.

A bats regression test (companion-survives-archipelago-restart.bats,
gated on ARCHY_ALLOW_DESTRUCTIVE=1) asserts the .228 failure mode
cannot recur: every installed companion has a unit file, services
stay active across systemctl --user restart archipelago, and a
deleted unit file is recreated within one reconcile tick.

Net delta: +941 / -363, but the +941 is mostly tests (~440 lines)
and the new declarative layer; the imperative tokio::spawn block and
its nginx-auth helper are gone, removing two failure classes
(orphan companions on archipelago crash, and post-start exec races
under tightly-confined cgroups) that previously needed manual SSH
recovery.

81c1613040 feat(container): BootReconciler — periodic reconcile loop for prod orchestrator
Step 5 of the rust-orchestrator migration. New file boot_reconciler.rs holds a
small Tokio task that calls ProdContainerOrchestrator::reconcile_all() on a
30-second cadence (answered design Q3).

  * BootReconciler::new(orch, interval, shutdown) — shutdown is an Arc<Notify>
    so callers can trigger a graceful exit without pulling in tokio-util.
  * run_forever(self) — does one reconcile immediately, then loops on
    tokio::select! { sleep_until | shutdown.notified() }. Shutdown interrupts
    the sleep but never an in-flight reconcile_all call.
  * Per-pass outcomes are logged at debug/warn; failures never propagate out
    because reconcile_all already absorbs per-app errors into ReconcileReport.

Four tokio::test(start_paused = true) tests verify the loop cadence against a
CountingRuntime test double:
  * initial_pass_fires_immediately — first reconcile runs with no delay
  * second_pass_fires_after_interval — second pass fires after exactly
    interval elapses in paused-clock time
  * shutdown_terminates_loop — notify_one() lets run_forever return
  * failure_in_one_pass_does_not_stop_loop — the loop keeps ticking even when
    the first pass had to install a missing container

Not wired into main.rs yet — that is Step 6. Re-exported from container::mod
as BootReconciler + RECONCILER_DEFAULT_INTERVAL for the wire-up step.
