fix: skeleton jitter + person count stability (hardware-verified)
* chore: update vendored ruvector to latest main (v2.1.0-40)

Was at v2.0.5-172 (f8f2c600a), now at v2.1.0-40 (050c3fe6f).
316 commits with new crates: ruvector-coherence, sona, ruvector-core,
ruvector-gnn improvements, and security hardening.

* feat: RuVector Phases 2+3 — temporal smoothing, kinematic constraints, coherence gating

Phase 2 (sensing server):
- Temporal keypoint smoothing via EMA (alpha=0.3) with coherence-adaptive blending
- Coherence scoring: running variance of motion_energy over 20 frames
  - Low coherence → reduce alpha to 0.1 (trust measurements less)
- Per-node prev_keypoints for frame-to-frame smoothing
- Bone length clamping (±20%) in derive_single_person_pose

Phase 3 (signal crate):
- SkeletonConstraints: Jakobsen relaxation (3 iterations) on 12-bone
  COCO-17 kinematic tree — prevents impossible skeletons
- CompressedPoseHistory: two-tier storage (hot f32 + warm i16 quantized)
  for trajectory matching and re-ID
- 8 new tests for constraints + history

Vendored ruvector updated to v2.1.0-40 (latest main, 316 commits).
Workspace deps remain at v2.0.4 (crates.io) until v2.1.0 is published.

647 tests pass across both crates (0 failures).

* fix(server): use max instead of sum for multi-node person aggregation

With nodes in the same room, each node sees the same people. Summing
per-node counts double-counted (2 nodes × 1 person = 2 persons).
Now uses max() so 2 nodes × 1 person = 1 person.

Verified on real hardware: COM6 (node 1) + COM9 (node 2) on ruv.net,
estimated_persons=1 with 1 person in room.

* fix(server): reduce skeleton jitter + raise person count thresholds

- EMA alpha 0.3→0.15, low-coherence 0.1→0.05
- Remove tick-based noise (main jitter source)
- Breathing 5x slower, extremity jitter 3x smaller, stride 2x smaller
- Person count 1→2 threshold 0.65→0.80
- Aggregation sum→max for same-room nodes

Verified on COM6+COM9: 1 person stable.
