docs: rewrite RuVector section with AI-focused framing

Browse Source 
Replace dry API reference table with AI pipeline diagram, plain-language
capability descriptions, and "what it replaces" comparisons. Reframes
graph algorithms and sparse solvers as learned, self-optimizing AI
components that feed the DensePose neural network.

All crates integrate with [RuVector v2.0.4](https://github.com/ruvnet/ruvector) for graph algorithms and neural network optimization.
#### AI Backbone: [RuVector v2.0.4](https://github.com/ruvnet/ruvector)
#### `wifi-densepose-ruvector` — ADR-017 Integration Layer
Raw WiFi signals are noisy, redundant, and environment-dependent. [RuVector](https://github.com/ruvnet/ruvector) is the AI intelligence layer that transforms them into clean, structured input for the DensePose neural network. It uses **attention mechanisms** to learn which signals to trust, **graph algorithms** that automatically discover which WiFi channels are sensitive to body motion, and **compressed representations** that make edge inference possible on an $8 microcontroller.
The `wifi-densepose-ruvector` crate ([`docs/adr/ADR-017-ruvector-signal-mat-integration.md`](docs/adr/ADR-017-ruvector-signal-mat-integration.md)) implements all 7 ruvector integration points across the signal processing and disaster detection domains:
```
Raw WiFi CSI (56 subcarriers, noisy)
|
+-- ruvector-mincut ---------- Which channels carry body-motion signal? (learned graph partitioning)
+-- ruvector-attn-mincut ----- Which time frames are signal vs noise? (attention-gated filtering)
+-- ruvector-attention ------- How to fuse multi-antenna data? (learned weighted aggregation)

v
Clean, structured signal --> DensePose Neural Network --> 17-keypoint body pose
--> FFT Vital Signs -----------> breathing rate, heart rate
--> ruvector-solver ------------> physics-based localization
```

The [`wifi-densepose-ruvector`](https://crates.io/crates/wifi-densepose-ruvector) crate ([ADR-017](docs/adr/ADR-017-ruvector-signal-mat-integration.md)) connects all 7 integration points:
| AI Capability | What It Replaces | RuVector Crate | Result |

| **Self-optimizing channel selection** | Hand-tuned thresholds that break when rooms change | `ruvector-mincut` | Graph min-cut adapts to any environment automatically |
| **Attention-based signal cleaning** | Fixed energy cutoffs that miss subtle breathing | `ruvector-attn-mincut` | Learned gating amplifies body signals, suppresses noise |
