ADR-081: implement Layers 1/2/4 end-to-end + host tests + QEMU hooks 

Turns the ADR-081 scaffolding into a working adaptive CSI mesh kernel:
Layer 1 radio abstraction has an ESP32 binding and a mock binding; Layer 2
adaptive controller runs on FreeRTOS timers; Layer 4 feature-state packet
is emitted at 5 Hz by default, replacing raw ADR-018 CSI as the default
upstream.

New files:
  firmware/esp32-csi-node/main/adaptive_controller_decide.c  (pure policy)
  firmware/esp32-csi-node/main/rv_radio_ops_mock.c           (QEMU binding)

  firmware/esp32-csi-node/tests/host/esp_err.h               (shim)
  firmware/esp32-csi-node/tests/host/.gitignore

Modified:
  adaptive_controller.c         — includes pure decide.c; emit_feature_state()
                                  wired into fast loop (200 ms = 5 Hz)

  rv_feature_state.h            — packed size corrected to 60 bytes
                                  (was incorrectly 80 in initial commit)
  main.c                        — mock binding registered under mock CSI
  CMakeLists.txt                — rv_radio_ops_mock.c under CSI_MOCK_ENABLED

`firmware/esp32-csi-node/main/rv_feature_state.h`: motion, presence,
respiration BPM/conf, heartbeat BPM/conf, anomaly score, env-shift

raw ADR-018 CSI as the default upstream stream (~99% bandwidth

motion, presence, respiration BPM/conf, heartbeat BPM/conf, anomaly
score, env-shift score, node coherence, quality flags, IEEE CRC32.
Replaces raw ADR-018 CSI as the default upstream stream (~99.7%
bandwidth reduction: 300 B/s at 5 Hz vs. ~100 KB/s raw).
- **Firmware: mock radio ops binding for QEMU** — New
`firmware/esp32-csi-node/main/rv_radio_ops_mock.c`, compiled only when
`CONFIG_CSI_MOCK_ENABLED`. Satisfies ADR-081's portability acceptance
test: a second `rv_radio_ops_t` binding compiles and runs against the
same controller + mesh-plane code as the ESP32 binding.
- **Firmware: feature-state emitter wired into controller fast loop** —
`adaptive_controller.c` now emits one 60-byte `rv_feature_state_t` per
fast tick (default 200 ms → 5 Hz), pulling from the latest edge vitals
and controller observation. This is the first end-to-end Layer 4/5
path for ADR-081.
- **Firmware: `csi_collector_get_pkt_yield_per_sec()` /
`_get_send_fail_count()` accessors** — Expose the CSI callback rate
and UDP send-failure counter so the ESP32 radio ops binding can
populate `rv_radio_health_t.pkt_yield_per_sec` and `.send_fail_count`,
closing the adaptive controller's observation loop.
- **Firmware: host-side unit test suite for ADR-081 pure logic** — New
`firmware/esp32-csi-node/tests/host/` (Makefile + 2 test files + shim
`esp_err.h`). Exercises `adaptive_controller_decide()` (9 test cases:
degraded gate on pkt-yield collapse + coherence loss, anomaly > motion,
motion → SENSE_ACTIVE, aggressive cadence, stable presence →
RESP_HIGH_SENS, empty-room default, hysteresis, NULL safety) and
`rv_feature_state_*` helpers (size assertion, IEEE CRC32 known
vectors, determinism, receiver-side verification). 33/33 assertions
pass. Benchmarks: decide() 3.2 ns/call, CRC32(56 B) 614 ns/pkt
(87 MB/s), full finalize() 616 ns/call. Pure function
`adaptive_controller_decide()` extracted to
`adaptive_controller_decide.c` so the firmware build and the host
tests share a single source-of-truth implementation.
- **Scripts: `validate_qemu_output.py` ADR-081 checks** — Validator
(invoked by ADR-061 `scripts/qemu-esp32s3-test.sh` in CI) gains three
checks for adaptive controller boot line, mock radio ops
registration, and slow-loop heartbeat, so QEMU runs regression-gate
Layer 1/2 presence.
- **Firmware: adaptive controller** — New
`firmware/esp32-csi-node/main/adaptive_controller.{c,h}` implements
the three-loop closed-loop control specified by ADR-081: fast

upstream therefore drops by ~99% (80 B × 5 Hz = 400 B/s) while preserving
all action-relevant state. This is what makes a 50-node deployment feasible
on a single-AP backhaul.

## Measured performance
Host-side benchmarks (`firmware/esp32-csi-node/tests/host/`), x86-64,
gcc `-O2`, 2026-04-19. Numbers are illustrative of algorithmic cost on
a modern CPU; on-target ESP32-S3 Xtensa LX7 at 240 MHz is ~5–10×
slower for bit-by-bit CRC and broadly comparable for the decide
function after inlining.
| Operation | Cost per call | Notes |

| `adaptive_controller_decide()` | **3.2 ns** (host) | O(1) policy, 9 branches evaluated |
| `rv_feature_state_crc32()` (56 B hashed) | **614 ns** (host) | 87 MB/s — bit-by-bit IEEE CRC32 |
| `rv_feature_state_finalize()` (full) | **616 ns** (host) | CRC-dominated |
Projected on-target cost at 5 Hz cadence:
| Budget | Value |
|--------------------------------------------|---------------------|
| Controller fast-loop tick work (ESP32-S3) | < 10 μs (est.) |
| CRC32 per feature packet (ESP32-S3) | ~3–6 μs (est.) |
| Feature-state emit cost @ 5 Hz | ~30 μs/sec (0.003%) |
| UDP send cost (existing stream_sender) | — unchanged — |
**Bandwidth:**
| Mode | Rate |
|---------------------------------------------|-------------|
| Raw ADR-018 CSI (pre-ADR-081) | ~100 KB/s |
| ADR-039 compressed CSI (Tier 1) | ~50–70 KB/s |
| ADR-039 vitals packet (32 B @ 1 Hz) | 32 B/s |
| **ADR-081 feature state (60 B @ 5 Hz)** | **300 B/s** |
**Memory:**

| Controller state (s_cfg + s_last_obs + …) | ~80 bytes |
| Feature-state emit packet (stack, per tick) | 60 bytes |
