ADR-081: adaptive CSI mesh firmware kernel + scaffolding
Introduces a 5-layer firmware kernel that reframes the existing ESP32
modules as components of a chipset-agnostic architecture and authorizes
adaptive control + a compact feature-state stream as the default upstream.
Layers:
L1 Radio Abstraction Layer — rv_radio_ops_t vtable + ESP32 binding
L2 Adaptive Controller — fast/medium/slow loops (200ms/1s/30s)
L3 Mesh Sensing Plane — anchor/observer/relay/coordinator (spec)
L4 On-device Feature Extr. — rv_feature_state_t (magic 0xC5110006)
L5 Rust handoff — feature_state default; debug raw gated

Default policy is conservative: enable_channel_switch and
enable_role_change are off, so behavior matches today's firmware
unless an operator opts in via menuconfig. The pure
adaptive_controller_decide() is exposed for offline unit tests.
Reuses (does not rewrite): csi_collector, edge_processing (ADR-039),
swarm_bridge (ADR-066), secure_tdm (ADR-032), wasm_runtime (ADR-040).
