feat(mat/tracking): add fingerprint re-ID + lib.rs integration (WIP)
- tracking/fingerprint.rs: CsiFingerprint for CSI-based survivor re-ID
across signal gaps. Weighted normalized Euclidean distance on breathing
rate, breathing amplitude, heartbeat rate, and location hint.
EMA update (α=0.3) blends new observations into the fingerprint.
- lib.rs: fully integrated tracking bounded context
- pub mod tracking added
- TrackingEvent added to domain::events re-exports
- pub use tracking::{SurvivorTracker, TrackerConfig, TrackId, ...}
- DisasterResponse.tracker field + with_defaults() init
- tracker()/tracker_mut() public accessors
- prelude updated with tracking types
Remaining: tracking/tracker.rs (SurvivorTracker aggregate root)
