* Add navi-offroute service (extraction #8 — the last one)
Faithful port of recon's /api/offroute (POST) + /api/mvum (GET) and the
runtime offroute modules into a new :8428 service. Closes the loop: after
this, navi-frontend talks only to navi-backend.
Ported: router.py (OffrouteRouter, EntryPointIndex, 4 route strategies,
in-Python MCP_Geometric least-cost path, Valhalla integration, per-request
osmium extract), mvum.py (MVUMReader over navi.db), cost.py, friction.py,
trails.py, and barriers.py (runtime BarrierReader/WildernessReader only).
NOT ported (per Phase A §3/§15): prototype.py (dead at runtime), barriers.py
build_*_raster (offline GDB→raster prep). DEM imported from shared/dem.py
(PR #9), not duplicated.
Behaviour-faithful changes: hardcoded paths/URLs → env vars; the
profile.offroute.* config (osm_pbf_path/postgis_dsn/densify_interval_m) →
dedicated env vars (router drops deployment_config). Both routes public (no
auth, matching recon). PADUS via libpq peer-auth DSN (dbname=padus) — NO
secret. Owns no DB.
15 hermetic tests (offroute validation + mocked-router shape + close-always;
fixture-SQLite MVUM roads/trails/fallback/null; admin auth + no-secrets +
probe shape). Full suite 119 passed / 1 skipped. Adds scikit-image + rasterio.

* navi-offroute: PR #10 review cleanups (4 faithful-port deviations)
1. trails.py — drop recon-era "Run the Phase B rasterization script"
reference from the not-found error (confusing in navi-offroute context).
2. friction.py — add FileNotFoundError-before-rasterio-open check to
match barriers/trails consistency.
3. mvum.py — remove dead try/except shapely import + warnings.warn at
2 sites (shapely is a hard pyproject dep; the fallback was unreachable).
4. router.py — declare psutil in pyproject, drop the silent fallback;
the MEMORY_LIMIT_GB safety check was silently disabled in prod.
Adds test_friction_reader_raises_file_not_found_when_missing (16 navi-offroute
tests; full suite 120 passed / 1 skipped).
