feat(ruview-unified): unified RF spatial world model P1 (ADR-273..278)

One shared representation instead of another isolated RF classifier: new
v2 leaf crate ruview-unified implementing all five ADR-273 pillars, plus
six ADRs with measured, grade-labeled results.

- Canonical RfTensor + fail-closed hardware adapter registry (802.11 CSI
  via wifi-densepose-core::CsiFrame, FMCW radar cubes, UWB CIR, 5G SRS);
  shared layout/gain/phase normalization proven by tests (ADR-274).
- Universal RF foundation encoder: CFO-aligned, median-scaled tokenizer;
  masked-reconstruction pretraining with hand-derived backprop verified
  against central finite differences (max rel err 1.31e-5 over all 12
  parameter groups); fusion contract z = Enc ⊙ σ(AgeEnc) + GeomEnc;
  task adapters under the 1% budget (129/268/387/2 params vs 40,856
  backbone), enforced by test.
- RF-aware Gaussian spatial memory: anisotropic primitives with per-band
  reflectivity, confidence-weighted fusion, decay, spatial-hash/semantic
  queries, closed-form Beer-Lambert channel gain (exact Friis on empty
  map), inverse gain updates (unseen 6.1 dB wall learned to <0.5 dB in
  20 observations), task-gated scene graph (ADR-275).
- Physics-guided synthetic RF worlds: image-method multipath (order ≤2),
  complex-permittivity Fresnel materials, emergent Doppler proven against
  the analytic phase rate, seeded ChaCha20 randomization of physics and
  hardware nuisances; byte-deterministic per seed (ADR-276).
- Edge sensing control plane: 802.11bf/ETSI-ISAC-aligned purposes/zones,
  fail-closed authorization, double-gated identity, retention bounds;
  BoundedEvent-only trust boundary makes raw RF export unrepresentable
  (ADR-277). Radar inverse rendering stays a gated research program
  (ADR-278, no code by design).

Anti-leakage acceptance pipeline (strict splits by room/day/person/
chipset/firmware/layout with independent disjointness verification):
presence F1 1.00 on held-out rooms and held-out chipset, degradation
0.0, ECE 0.012, p95 latency 2.0 ms debug / 105 µs release — ALL
SYNTHETIC until P2 real-data validation.

Benchmarks + optimization pass: channel_gain 139→27 µs (O(1) in map
size via segment-corridor AABB sweep), observe_link 305→74 µs, DFT
twiddle plan 4.9x; hash/linear crossover (~4k Gaussians) reported
honestly.

Tests: ruview-unified 66 unit + 3 acceptance, 0 failed; workspace
3,771 passed 0 failed (--exclude wifi-densepose-desktop: GTK headers
unavailable in this container). Python proof: VERDICT PASS. Also
gitignore sensing-server test-run artifacts (incl. generated
session-secret).
