ruv f751740d3d docs(adr): ADR-116 — Home Assistant + Matter as a Cognitum Seed cog
Proposes `cog-ha-matter` as a Cognitum Seed cog packaging the
ADR-115 HA-DISCO + HA-MIND surfaces as a first-class Seed-installable
artifact, rather than configuration of an external sensing-server.

P1 — research dossier in progress (deep-researcher agent), output at
`docs/research/ADR-116-ha-matter-cog-research.md`.

Seed-native enhancements vs the ADR-115 sensing-server flag:
  - Embedded mosquitto (optional, for Seeds without external broker)
  - mDNS service advertisement (_ruview-ha._tcp)
  - RuVector-backed semantic-primitive thresholds (SONA adaptation,
    per-home learning rather than static YAML)
  - Ed25519 witness chain for state transitions (regulated deployments)
  - OTA firmware coordination for the mesh's ESP32-C6 nodes
  - Multi-Seed federation via ADR-110 ESP-NOW substrate (≤100 µs
    sync enables cross-Seed dedup of events like falls in shared rooms)

7 open questions tracked for the research dossier to answer:
Matter Bridge vs Matter Root, Thread Border Router feasibility,
HACS value-add, CSA cert cost/timeline, cog binary RAM budget,
ruvllm latency, HIPAA/FDA classification.

10 implementation phases scaffolded. Tracking issue to file once
research lands. PR for the cog binary in P2.
