feat(ruvector): implement ADR-017 as wifi-densepose-ruvector crate + fix MAT warnings
New crate `wifi-densepose-ruvector` implements all 7 ruvector v2.0.4
integration points from ADR-017 (signal processing + MAT disaster detection):
signal::subcarrier — mincut_subcarrier_partition (ruvector-mincut)
signal::spectrogram — gate_spectrogram (ruvector-attn-mincut)
signal::bvp — attention_weighted_bvp (ruvector-attention)
signal::fresnel — solve_fresnel_geometry (ruvector-solver)
mat::triangulation — solve_triangulation TDoA (ruvector-solver)
mat::breathing — CompressedBreathingBuffer 50-75% mem reduction (ruvector-temporal-tensor)
mat::heartbeat — CompressedHeartbeatSpectrogram tiered compression (ruvector-temporal-tensor)
16 tests, 0 compilation errors. Workspace grows from 14 → 15 crates.
MAT crate: fix all 54 warnings (0 remaining in wifi-densepose-mat):
- Remove unused imports (Arc, HashMap, RwLock, mpsc, Mutex, ConfidenceScore, etc.)
- Prefix unused variables with _ (timestamp_low, agc, perm)
- Add #![allow(unexpected_cfgs)] for onnx feature gates in ML files
- Move onnx-conditional imports under #[cfg(feature = "onnx")] guards
README: update crate count 14→15, ADR count 24→26, add ruvector crate
table with 7-row integration summary.
Total tests: 939 → 955 (16 new). All passing, 0 regressions.
