feat(rufield): rufield-viewer dashboard — completes ADR-260 §27.9

Bumps the vendor/rufield submodule to include the new rufield-viewer crate
(Axum + vanilla JS read-only dashboard streaming the deterministic
SyntheticSim→fusion camera-free room-intelligence demo: live room state,
P0–P5 privacy-badged event log, fusion graph, signed-receipt viewer, behind
a permanent SYNTHETIC banner). All ADR-260 §27 criteria 1–10 now PASS.
Read-only demo viewer, not device management (real-adapter milestone later).
rufield repo now 7 crates / 72 tests.

 ### Added
+- **RuField `rufield-viewer` web dashboard — completes ADR-260 §27.9 (all §27 criteria 1–10 now PASS).** A read-only Axum + vanilla-JS dashboard (no build step — `cargo run -p rufield-viewer`) that streams the deterministic SyntheticSim→fusion camera-free room-intelligence demo: live room-state inferences with confidence, a scrolling event log where every event carries its modality + a colour-coded **P0–P5 privacy badge**, the fusion graph (supporting=green / contradicting=red per inference), and a click-to-open **provenance-receipt modal** (sha256 + ed25519 signer + verified ✓ / fusable ✓) — behind a permanent, undismissable `SYNTHETIC — simulated sensors, no hardware` banner. Endpoints `/` · `/app.js` · `/health` · `/api/run` (full deterministic JSON) · `/events` (SSE). 12 new tests. Honest scope: a read-only SYNTHETIC demo viewer, **not** a device-management console — fleet/real-adapter management is a separate later milestone. Lives in [`ruvnet/rufield`](https://github.com/ruvnet/rufield) (`crates/rufield-viewer`, repo now 7 crates / 72 tests); `vendor/rufield` submodule bumped to include it.
 - **ADR-261: RuVector graph-ANN index — a real HNSW baseline + a SymphonyQG-style quantized variant, MEASURED (honest negative).** Closes the [ADR-156 §5 #1](docs/adr/ADR-156-ruvector-fusion-beyond-sota.md) gap: the SymphonyQG (SIGMOD 2025) **3.5–17× QPS-over-HNSW** claim was CLAIMED-only because **no HNSW baseline existed to compare against**. This adds one. New pure-Rust, `--no-default-features`-buildable modules in `wifi-densepose-ruvector`: `hnsw.rs` (a correct float HNSW — Malkov & Yashunin: multi-layer NSW graph, `ef_construction`/`ef_search`, Algorithm-4 neighbour selection, **seeded-deterministic** level assignment via SplitMix64, L2 + cosine, full degenerate-case guards), `hnsw_quantized.rs` (the SymphonyQG-style variant — the **same** graph traversed by a cheap **1-bit Hamming** score over the RaBitQ Pass-2 rotated sign code, then **exact-float rerank**), `ann_measure.rs` + `benches/ann_bench.rs` (one shared deterministic planted-cluster fixture; the `ann_bench_report` test is the source of truth). **MEASURED (dim=128, N=10k, K=10, `--release`):** float HNSW = **~25× QPS over linear scan at recall ≥0.99** (the baseline this gap needed; recall@10 correctness gate ≥0.95 holds, L2 + cosine). **Honest negative:** the 1-bit quantized traversal is **too coarse to beat float HNSW at equal recall at this scale** — its best recall is **0.738**, never reaching the ≥0.90 equal-recall point, so there is **no QPS win** over float HNSW; the 3.5–17× is **not reproduced** by our 1-bit construction here. The recall gate also **caught a real index-out-of-bounds bug** in the insert path (disclosed in ADR-261 §4). Caveat: this is **our** HNSW + **our** 1-bit quant, not SymphonyQG's exact system — it tests the *direction* of the claim, with the expected crossover at large N + a multi-bit traversal code. **We did not tune to manufacture a speedup.** +20 tests (ruvector lib 131→151, 0 failed). ADR-156 §5 #1 / §8 backlog: CLAIMED → **MEASURED-direction-tested**. Python deterministic proof unchanged (off the signal proof path).
 - **ADR-261 Milestone-2: multi-bit quantized HNSW traversal + large-N scaling study — MEASURED (honest negative).** Extends ADR-261's quantized index from 1-bit to **`b`-bit-per-dimension** (`b ∈ {1,2,4}`, 16/32/64 B/node) over the Pass-2 rotated coordinates, and runs a deterministic scaling study (N ∈ {10k, 100k, 250k}) to test M1's *prediction* of a large-N crossover. **Result: no crossover at any measured (N, b), and the trend refutes the prediction.** At N=10k more bits lift the equal-recall QPS ratio (0.19×→0.46×→0.48×) and let b≥2 reach the 0.90 recall bar 1-bit missed — but quant stays slower than float HNSW at equal recall; at N=100k/250k quant recall *collapses* (b=4: 1.000→0.788→0.624, never ≥0.90) while float holds ≥0.92 (denser graph → low-bit codes can't separate near-neighbours, beam goes off-path faster than the float-distance saving repays). Caveat: our HNSW + our per-node multi-bit code, not SymphonyQG's RaBitQ-fused graph — refutes the *direction* at ≤250k, not their million-scale numbers. ruvector lib **151→156** (+5 tests; `scaling_report` `#[ignore]` produced the table). A published negative with the mechanism explained. ADR-261 §11.
 - **ADR-260: RuField MFS — the open specification for camera-free multimodal field sensing.** A common event / tensor / calibration / privacy / provenance model that sits *above* WiFi CSI/CIR/BFLD, UWB, BLE Channel Sounding, mmWave radar, ultrasound, subsonic, infrared, and future quantum sensors (each modality emits a normalized `FieldEvent` → `FieldTensor` → `FusionGraph` → `PrivacyClass` → `ProvenanceReceipt`). Published as a **standalone repo** [`ruvnet/rufield`](https://github.com/ruvnet/rufield) and vendored here as the `vendor/rufield` submodule (the `vendor/rvcsi` pattern — not a `v2/` workspace member). The v0.1 reference stack is a self-contained 6-crate Rust workspace (`rufield-core`, `-provenance` [sha256 + ed25519], `-privacy` [P0–P5 guard], `-adapters` [deterministic `SyntheticSim` across wifi_csi/mmwave_radar/infrared_thermal], `-fusion` [graph + TOML weighted-Bayes rules → 7 room-state inferences], `-bench` [deterministic runner + the §31 acceptance test]). **60 tests / 0 failed, clippy-clean.** §27 acceptance criteria 1–8 and 10 PASS; the live dashboard (9) is deferred. **All benchmark metrics are SYNTHETIC** (scored against the simulator's own ground truth — presence/breathing/bed_exit/room_transition F1 = 1.000, nocturnal_scratch 0.923 reported honestly, p95 latency ~0.01 ms, provenance coverage 100%, 0 privacy violations) — they prove the pipeline recovers known truth, **not** field accuracy; real hardware adapters (ESP32 CSI, mmWave, thermal IR) are a documented roadmap item, none validated in v0.1. The Python deterministic proof is unchanged (rufield is off the signal-processing proof path).
