research(R6.2.3): chest-centric placement — +26.9 pp coverage gain for vital-signs cogs (#726) 
Direct follow-up from R6.1 (chest contributes 27.6% of CSI energy,
5x per-limb value, limbs are confound not signal).

R6.2.3 re-runs R6.2's placement search with chest-only target zones
(40x40 cm patches at expected chest positions) vs body-footprint zones
(R6.2's default full-area definition).

Headline result:

| Configuration              | Coverage | Placement                  |
|----------------------------|---------:|----------------------------|
| Body-centric (R6.2 default)|   49.3%  | (4.25,0)-(0,3.25), 5.35 m  |
| CHEST-CENTRIC (R6.2.3 new) |   82.4%  | (2.0,0)-(4.5,5),   5.59 m  |

Cross-eval:
- Body-optimal on chest zones:    55.5%
- Chest-targeting GAIN on chest:  +26.9 pp
- Chest-optimal on body zones:    40.3% (-9.0 pp loss)

The two strategies are genuinely different. Same engine, different
zones.

Per-cog deployment recommendation surfaced:
- --target-mode=body  (default): cog-person-count, cog-pose, cog-presence
- --target-mode=chest (new):     cog-vital-signs, cog-breathing, cog-HR
- --target-mode=extremity (future): gesture detection

~20 LOC change to R6.2 CLI.

R14 vertical-specific:
- V1 stress-responsive lighting:        chest mode
- V2 adaptive HVAC (presence+breathing): mixed
- V3 attention-respecting conversation:  chest mode

R6.2.3 surfaces a per-cog config that empathic-appliance products
need at install time.

Why placements differ: when target ~ envelope width, envelope can cover
it entirely; when target >> envelope, placement must compromise. 40 cm
Fresnel envelope @ 5 m link comfortably covers 40 cm chest patches but
must spread to cover 3 m^2 bed.

Composes:
- R6.1 motivated this tick
- R6.2 / R6.2.1 / R6.2.2 -- orthogonal extensions
- R14 V1/V3 should use chest mode
- R12 PABS improves body-position-detection scenarios

Honest scope:
- Chest positions approximated
- 2D still (3D chest-centric = R6.2.3.1 follow-up)
- Single subject (multi-subject = union of chest envelopes)
- Per-cog zone schema is deployment-time
