a6bc5106bc Cut Planner over to dedicated BRouter host
Adds BROUTER_URL=http://10.0.1.10:17777 (vSwitch) to SOPS so the Planner
starts routing through the dedicated host's Caddy sidecar instead of the
in-tree flagship BRouter. Flagship BRouter stays warm for the 48h
soak/rollback window.

Pre-flight from the flagship confirmed the new host answers 200 with the
auth header and 403 without.

Mark cutover tasks 7.1-7.3 complete
End-to-end verified on the dedicated host:
- All 4 containers up (brouter 1.7.9, caddy, cadvisor, promtail)
- Planet segments seeded (~10 GB in 1 min, not hours)
- Auth enforced: 403 without header, 200 with header from flagship
- Planner live with BROUTER_AUTH_TOKEN wired (module-level guard passed)

Remaining:
- 7.4 Flip BROUTER_URL in SOPS (the actual cutover)
- 7.5 Remove flagship brouter after 48h soak
- 7.6 Document rollback in final PR description

BRouter host observability + docs
Lands sections 6 and 8 of relocate-brouter-to-dedicated-host on top
of the host compose in #291.

## Observability (section 6)

- **Prometheus**: new `brouter-cadvisor` job scraping
  `10.0.1.10:8080` over the vSwitch, labeled `host="brouter"`.
- **cAdvisor sidecar** on the dedicated host's compose
  (`--docker_only --whitelisted_container_labels=trails.cool.service`)
  so metrics only cover trails containers, never the operator's
  unrelated workloads on the shared box.
- **Promtail sidecar** on the dedicated host, Docker SD with relabel-
  drop on missing `trails.cool.service` label, pushing to flagship
  Loki at `http://10.0.0.2:3100/loki/api/v1/push`.
- **Flagship compose**: Loki now publishes port 3100 on the vSwitch
  IP only (10.0.0.2:3100) — Hetzner Cloud firewall blocks it from
  the public internet.
- **Grafana dashboard**: `brouter.json` — scrape up/down, request
  rate (from Planner-side `brouter_request_duration_seconds`),
  p50/p95/p99, container memory/CPU, Loki logs panel.
- **Alert**: `brouter-scrape-down` fires on
  `up{job="brouter-cadvisor"} < 1 for 2m`; `noDataState: Alerting`
  so a total scrape failure still pages.

Operator needs one UFW rule on the dedicated host for the cAdvisor
port — documented in `infrastructure/brouter-host/README.md`.

## Documentation (section 8)

- `CLAUDE.md` — hosts table + updated deployment table with SSH
  targets per workflow; BRouter host SSH is `-p 2232 trails@...`,
  different key.
- `docs/architecture.md` — Hosting section rewritten to cover both
  hosts, vSwitch boundary, and the observability-scoping rationale
  for the shared dedicated host.
- `docs/deployment.md` (new) — full operator runbook: host layout,
  first-time BRouter provisioning, SOPS rotation (including the
  macOS `SOPS_AGE_KEY_FILE` gotcha), cutover procedure with
  rollback, manual workflow triggers.

Task 8.4 (infrastructure/README.md) skipped: that file doesn't
exist and the ground is covered by brouter-host/README.md +
docs/deployment.md.

## Validation

- `docker compose config` on both the flagship and brouter-host
  compose files — both validate.
- `pnpm typecheck`, `pnpm lint`, `pnpm test` — all clean (full
  turbo cache hits; no code changes in this commit).

BRouter host compose + Planner auth + cd-brouter rewrite
Lands sections 3-5 of the relocate-brouter-to-dedicated-host change:
everything needed to run BRouter on the dedicated Hetzner Robot host
and have the Planner talk to it with the shared-secret header. Does
NOT flip the cutover — the flagship BRouter stays warm during soak.

## BRouter host compose (section 3)

New `infrastructure/brouter-host/` — a standalone compose project that
runs as the `trails` user on `ullrich.is`:

- `docker-compose.yml` — brouter + caddy sidecar. BRouter has no host
  port; caddy binds only to `10.0.1.10:17777` (vSwitch IP). Every
  service explicitly overrides the host's default Loki logging driver
  to `json-file` so logs don't leak to the operator's personal Loki.
- `Caddyfile` — single-purpose reverse proxy that requires
  `X-BRouter-Auth: ${BROUTER_AUTH_TOKEN}` on every request. `auto_https
  off` (vSwitch-only); default access log format omits request
  headers, so the token is never written to disk.
- `download-segments.sh` — crawls brouter.de, pulls planet-wide RD5
  tiles via `wget -N` (incremental). Idempotent, safe to cron.
- `README.md` — one-shot provisioning + token rotation + rollback
  notes.

`docker/brouter/Dockerfile` is patched to honor `JAVA_OPTS` (was
hardcoded `-Xmx1024M` in CMD). Default keeps the flagship's current
heap; compose on the dedicated host overrides to `-Xmx8g` for planet
scale on a 32 GB box.

## Planner shared-secret header (section 4)

`apps/planner/app/lib/brouter.ts`:

- Module-level guard: throws at startup in production if
  `BROUTER_AUTH_TOKEN` is unset.
- `authHeaders()` helper (reads env at call time, so tests can
  `vi.stubEnv` without module reset).
- Header attached on both `computeRoute` (per-segment) and
  `computeSegmentGpx`.

3 new unit tests cover header attachment + the no-token path.

`infrastructure/docker-compose.yml` passes `BROUTER_AUTH_TOKEN` to
the Planner service, and makes `BROUTER_URL` overridable via SOPS so
the cutover is a one-variable flip.

## cd-brouter workflow (section 5)

Rewritten to deploy to the dedicated host:

- SSH as `trails@${BROUTER_DEPLOY_HOST}` on port
  `${BROUTER_DEPLOY_SSH_PORT}` (2232) using
  `${BROUTER_DEPLOY_SSH_KEY}`.
- Decrypts SOPS, extracts ONLY `BROUTER_AUTH_TOKEN` into a `.env`
  file, scp'd alongside the compose project.
- `paths:` trigger now includes `infrastructure/brouter-host/**`.
- Segment download is NOT run here — first-time seed is a manual
  operator step (multi-hour). Routine re-runs are cron-able on the
  dedicated host.
- Grafana annotation step preserved (reaches flagship Grafana as
  before).

## What's NOT here

- `brouter:` service on the flagship is intentionally left in place
  (removed in section 7.5 after the 48 h soak window post-cutover).
- Observability (section 6) — Prometheus scrape + Loki shipping from
  the dedicated host — comes in a follow-up PR.
- Cutover itself (section 7) — flip `BROUTER_URL`, verify, remove the
  flagship brouter — is an operator action gated on first-time
  provisioning + smoke testing.

## Verification

`pnpm typecheck && pnpm lint && pnpm test` all clean; planner build
passes (the CI regression from #286 was fixed in #290).

Add BROUTER_AUTH_TOKEN to app secrets (SOPS)
Adds the shared-secret header value consumed by the Planner
(as X-BRouter-Auth outbound) and by the BRouter host's Caddy
sidecar (enforced inbound). Lives in secrets.app.env only;
cd-brouter.yml will also read from this file, making it the
single source of truth. secrets.infra.env is intentionally NOT
updated — cd-infra no longer touches BRouter after the move.

Add Hetzner vSwitch network for BRouter relocation
Adds an OpenSpec change scoping the relocation of BRouter from the
co-located flagship (cx23, 4 GB RAM, 40 GB SSD, Europe segments only) to
a dedicated Hetzner Robot host in the same datacenter, with private
connectivity over Hetzner vSwitch #80672 (VLAN 4000).

This first PR only lays the network prerequisite:

- Terraform: a Hetzner Cloud Network (10.0.0.0/16) with a cloud subnet
  (10.0.0.0/24) hosting the flagship at 10.0.0.2, and a vSwitch subnet
  (10.0.1.0/24) bridged to Robot VLAN 4000. The dedicated host's VLAN
  sub-interface (10.0.1.10 on enp4s0.4000) is configured out-of-band via
  netplan and is not Terraform-managed.
- lifecycle { ignore_changes = [user_data] } on the flagship server to
  prevent the Hetzner provider's post-1.45 user_data hash drift from
  triggering a spurious full-server replacement on unrelated applies.
- OpenSpec change with proposal, design, specs (delta for
  brouter-integration / infrastructure / observability /
  security-hardening), and tasks; Section 1 (pre-flight) is checked off
  with operator notes.

Verification: ping both directions across the vSwitch is 0% loss,
sub-ms latency; dedicated host's VLAN config persists across reboot
(verified ~60 s to restore private reachability).

Follow-up PRs will land the BRouter host compose project, Planner
shared-secret header, CD workflow retarget, observability wiring, and
the cutover.
