feat(train): Add ruvector integration — ADR-016, deps, DynamicPersonMatcher
- docs/adr/ADR-016: Full ruvector integration ADR with verified API details from source inspection (github.com/ruvnet/ruvector). Covers mincut, attn-mincut, temporal-tensor, solver, and attention at v2.0.4. - Cargo.toml: Add ruvector-mincut, ruvector-attn-mincut, ruvector-temporal- tensor, ruvector-solver, ruvector-attention = "2.0.4" to workspace deps and wifi-densepose-train crate deps. - metrics.rs: Add DynamicPersonMatcher wrapping ruvector_mincut::DynamicMinCut for subpolynomial O(n^1.5 log n) multi-frame person tracking; adds assignment_mincut() public entry point. - proof.rs, trainer.rs, model.rs, dataset.rs, subcarrier.rs: Agent improvements to full implementations (loss decrease verification, SHA-256 hash, LCG shuffle, ResNet18 backbone, MmFiDataset, linear interp). - tests: test_config, test_dataset, test_metrics, test_proof, training_bench all added/updated. 100+ tests pass with no-default-features. https://claude.ai/code/session_01BSBAQJ34SLkiJy4A8SoiL4
