feat(cli): wire ADR-151 enroll / train-room / room-status / room-watch

Integrates the wifi-densepose-calibration crate into the CLI as four
subcommands driving the full Stage 2–5 pipeline against a live ESP32 raw-CSI
stream (edge_tier=0):

- enroll: walks the guided anchor sequence, gates each capture against the
  ADR-135 baseline deviation (re-prompts bad anchors), writes labelled features
- train-room: fits the SpecialistBank from the enrollment, persists JSON
- room-status: prints a trained bank's summary
- room-watch: live mixture-of-specialists readout (presence/posture/breathing/
  heart/restless) over a rolling window, with anomaly veto + STALE flagging

Per-frame scalar is the mean CSI amplitude (carries presence/motion + breathing
modulation). Validated end-to-end on the live ESP32 (COM8, edge_tier=0): the
real parser → feature extraction → runtime detected breathing (~16–31 BPM) on
hardware. Full multi-anchor enrollment accuracy requires the operator to perform
the poses; phase-based breathing extraction is a noted refinement.

48 tests pass (29 calibration + 19 CLI).
