ruv c9f005c360 cog-ha-matter (ADR-116 P3): wire publisher::spawn into main.rs
P3 closes the publisher wiring loop. `main.rs` now:

  1. builds `PublisherInputs` from CLI args via the pure helper
     extracted last iter,
  2. opens a `broadcast::channel::<VitalsSnapshot>(256)`,
  3. calls `runtime::spawn_publisher(inputs, rx)` — a thin
     wrapper around ADR-115's `publisher::spawn` that owns the
     `Arc<MqttConfig>` wrap,
  4. holds the tx side so the channel stays open until P3.5
     wires the sensing-server bridge,
  5. awaits Ctrl-C or unexpected publisher exit (logged at WARN).

Two new tests:
  * `spawn_publisher_returns_live_handle_without_broker` — proves
    the wiring compiles and the rumqttc event loop survives an
    unreachable broker (it retries internally; we abort the handle
    inside 100 ms). Catches breakage from a future refactor that
    accidentally pre-validates host reachability.
  * `default_state_channel_capacity_is_reasonable` — locks the
    `DEFAULT_STATE_CHANNEL_CAPACITY = 256` default; a regression to
    e.g. 1 would surface here instead of as a dropped frame in
    production under bursty multi-Seed federation.

12/12 cog-ha-matter tests green (10 → 12).

ADR-116 phase table: P3 flipped from "in progress" to  wiring done,
with the P3.5 follow-up (sensing-server `/v1/snapshot` WS bridge)
explicitly named.
