feat(adr-115): P6 + P10 — runnable wiring example + witness bundle (VERIFIED)

## P6 — Wiring example

`v2/crates/wifi-densepose-sensing-server/examples/mqtt_publisher.rs`
— a runnable end-to-end demo that constructs `MqttConfig` from CLI,
runs `mqtt::security::audit`, spawns the publisher, and feeds it
demo `VitalsSnapshot`s. Every line is the production-wiring blueprint
for `main.rs` when `args.mqtt` is true. Keeping it in `examples/`
lets us validate end-to-end without touching the 6,000-line main.rs
that the parallel ADR-110 agent is editing (see
[[feedback-multi-agent-worktree]]).

Run it:

    cargo run --release -p wifi-densepose-sensing-server \
        --features mqtt --example mqtt_publisher -- \
        --mqtt --mqtt-host 127.0.0.1

Compile-checked clean under `--features mqtt`.

## P10 — Witness bundle (VERIFIED)

`scripts/witness-adr-115.sh` — generator that captures everything a
reviewer needs to verify ADR-115 from the receiving end:

- ADR-115 design doc snapshot
- `integration-docs/` — home-assistant.md + semantic-primitives-metrics.md
- `test-results/lib-tests.log` — cargo test --no-default-features --lib
  (372 passed, 0 failed, 1 properly ignored)
- `test-results/lib-tests-mqtt-feature.log` — under --features mqtt
- `test-results/integration-tests.log` — opt-in via RUVIEW_RUN_INTEGRATION=1
- `bench-results/criterion-*.log` — opt-in via RUVIEW_RUN_BENCH=1
- `manifest/source-hashes.txt` — SHA-256 of every ADR-115 source file
- `manifest/git-head.txt` + `git-head-commit.txt` — exact source commit
- `VERIFY.sh` — self-verification script; recipient runs `bash VERIFY.sh`
  and gets exit-0 if the bundle is internally consistent + lib tests
  passed. Local self-test PASSED end-to-end on this commit.
- `WITNESS-LOG-115.md` — per-phase attestation matrix (P1–P10 status)

Bundle dropped at `dist/witness-bundle-ADR115-<sha>-<ts>.tar.gz`.

## Docs

- `docs/user-guide.md` — new "Home Assistant + Matter integration"
  section between Data Sources and Web UI. 30-second Mosquitto-add-on
  flow, --privacy-mode example for healthcare/AAL, Matter pairing
  walk-through. Links back to docs/integrations/home-assistant.md
  for the full reference.
- `CHANGELOG.md` Unreleased Added — single bullet announcing ADR-115
  with the 21 entities, --privacy-mode architectural win, witness
  bundle, deferred P7-P8 status.

## Phase status

### Added
- **Home Assistant + Matter integration (ADR-115).** New `--mqtt` and `--matter` flags on `wifi-densepose-sensing-server` expose the full sensing capability set to any Home Assistant install via MQTT auto-discovery (HA-DISCO) and to any Matter controller (Apple Home / Google Home / Alexa / SmartThings) via a built-in Matter Bridge (HA-FABRIC). Includes 21 entity kinds — 11 raw signals + 10 semantic primitives (someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition). The semantic primitives run server-side so `--privacy-mode` strips HR/BR/pose values from the wire while still publishing the inferred *states* — the architectural win for healthcare and AAL deployments. Three starter HA Blueprints (distress notify, hallway dim on sleeping, wake routine on bed exit), Lovelace dashboard examples, mTLS support, 32 KB payload-size cap, MQTT-wildcard topic-injection rejection. **372 tests** cover the implementation. See [`docs/integrations/home-assistant.md`](docs/integrations/home-assistant.md), [`docs/integrations/semantic-primitives-metrics.md`](docs/integrations/semantic-primitives-metrics.md), [`docs/adr/ADR-115-home-assistant-integration.md`](docs/adr/ADR-115-home-assistant-integration.md), and tracking issue [#776](https://github.com/ruvnet/RuView/issues/776). Matter SDK spike (P7) and CSA-certification path (P10) deferred to v0.7.1+ per ADR §9.10. Try it: `cargo run -p wifi-densepose-sensing-server --features mqtt --example mqtt_publisher -- --mqtt --mqtt-host 127.0.0.1`.

## Home Assistant + Matter integration
Full design + operator guide: [`docs/integrations/home-assistant.md`](integrations/home-assistant.md) (ADR-115).
### 30-second Mosquitto-add-on flow
1. Inside Home Assistant, install the **Mosquitto broker** add-on from the Add-on Store and start it.
2. In HA, **Settings → Devices & Services → Add Integration → MQTT**, point at the broker.
3. Start the sensing-server with MQTT:
```bash
docker run --rm --net=host ruvnet/wifi-densepose:0.7.0 \
--source esp32 --mqtt --mqtt-host <ha-host-ip>
```
4. Within ~5 seconds HA auto-creates one **device** per RuView node with 21 entities: 11 raw signals (presence, person count, HR, BR, motion, fall, RSSI, zones, pose, …) plus 10 semantic primitives (someone-sleeping, possible-distress, room-active, elderly-inactivity-anomaly, meeting, bathroom, fall-risk, bed-exit, no-movement, multi-room-transition).
### Privacy mode for healthcare / AAL
```bash
sensing-server --mqtt --mqtt-host <broker> --mqtt-tls --privacy-mode
```
`--privacy-mode` strips heart rate, breathing rate, and pose keypoints from MQTT **and** Matter — they never reach the wire. Semantic primitives stay published because they're inferred *states* server-side, not biometric *values*. This is the architectural win that makes ADR-115 healthcare- and enterprise-deployable.
### Matter Bridge (Apple Home / Google Home / Alexa / SmartThings)
```bash
sensing-server --matter --matter-setup-file /var/run/ruview-matter.txt
```
Open `/var/run/ruview-matter.txt` for the Matter pairing QR / 11-digit setup code. Scan it from Apple Home / Google Home / your HA Matter integration. RuView appears as a Bridged Device with one occupancy endpoint per node + per zone, plus a momentary switch for fall events.
Detailed entity reference, blueprint catalog, troubleshooting recipe matrix: see [`docs/integrations/home-assistant.md`](integrations/home-assistant.md).

//! ADR-115 P6 — minimal runnable example wiring the MQTT publisher
//! against a broadcast channel of `VitalsSnapshot`s.
//!
//! Run with:
//! cargo run --release -p wifi-densepose-sensing-server \
//! --features mqtt --example mqtt_publisher -- \
//! --mqtt --mqtt-host 127.0.0.1
//!
//! Then in another terminal:
//! mosquitto_sub -h 127.0.0.1 -t 'homeassistant/#' -v
//!
//! You should see one HA discovery `config` topic per entity per node
//! land within a second of startup, followed by `state` topics ticking
//! at the configured rates.
//!
//! This example is the production-wiring blueprint for `main.rs`:

//! `args.mqtt` is true. Keeping it in `examples/` lets us validate the
//! wiring end-to-end without touching the 6000-line main.rs (which is
