sjg 319e935d97 [feat](trx-server): wire SoapySDR backend and AudioSource into server startup
- Call validate_sdr() at startup and abort on errors (SDR.md §11)
- Build SoapySdrRig with full [[sdr.channels]] config when access_type is
  "sdr"; subscribe to its primary-channel PCM sender before handing the
  pre-built rig to the rig task via RigTaskConfig.prebuilt_rig
- Skip cpal capture when an SDR audio source is available; bridge the
  SdrPipeline PCM broadcast into pcm_tx so all decoder tasks are unchanged
- Add trx-backend-soapysdr optional dep and soapysdr feature to trx-server
- Add prebuilt_rig field to RigTaskConfig so rig_task skips the registry
  factory when a pre-built rig is supplied by main

Marks SDR-08 complete.

sjg dc3fd63a83 [test](trx-server): add SDR config validation unit tests
Adds 12 unit tests for ServerConfig::validate_sdr() covering: minimal
valid config, non-SDR skip, empty/missing args, zero sample_rate,
channel IF out-of-range (positive, negative, exactly at Nyquist), dual
stream_opus, tx_enabled with SDR backend, duplicate decoder, and
multiple simultaneous errors. Marks SDR-11 complete in SDR.md.

sjg 1be5b3d4c2 [feat](trx-backend-soapysdr): implement SoapySdrRig with AudioSource and DSP wiring
Replace the stub SoapySdrRig with a full implementation: wire up SdrPipeline
from dsp.rs, implement AudioSource::subscribe_pcm on the primary channel,
add gain control (manual/auto with fallback warning), and track primary
channel freq/mode so set_freq/set_mode update the live DSP pipeline.

sjg 1353e2a29b [test](trx-backend-soapysdr): add demodulator unit tests
Add 9 unit tests covering all demodulators in demod.rs: USB/LSB/Passthrough
real-part extraction, AM DC removal and varying-envelope, FM tone frequency
and silence, CW peak normalisation, mode mapping, and empty-input safety.

sjg 5090ab71b3 [feat](trx-backend-soapysdr): implement IQ DSP pipeline (mixer/FIR/decimate/demod)
Add dsp.rs with IqSource trait abstraction, MockIqSource, windowed-sinc
FIR low-pass filter, ChannelDsp (mixer/decimate/demod/frame-accumulator),
and SdrPipeline which spawns a dedicated IQ read thread. No soapysdr crate
dependency; the real device will be wired in SDR-07.

sjg db6dff304e [feat](trx-backend-soapysdr): implement demodulators (USB/LSB/AM/FM/CW)
Add demod.rs with Demodulator enum and per-mode demodulate() implementations:
USB/Passthrough (real part), LSB (real part, IF negated upstream), AM
(envelope, DC removal, peak normalisation), FM/WFM (quadrature discriminator
scaled by 1/π), CW (magnitude envelope, peak normalised). Marks SDR-05 done.

sjg 04f8fd019a [docs](trx-rs): document SDR backend configuration options
Add [sdr], [sdr.gain], and [[sdr.channels]] sections to CONFIGURATION.md,
extend [rig.access] with type = "sdr" / args, add CLI override note, and
append a commented SoapySDR example block to trx-server.toml.example.
Mark SDR-09 as complete in SDR.md.

sjg 2ee217a1a1 [feat](trx-backend-soapysdr): add crate scaffold with RigCat stub
Introduces the trx-backend-soapysdr crate with a compilable SoapySdrRig
struct that satisfies the Rig + RigCat trait bounds.  RX methods
(get_status, set_freq, set_mode, get_signal_strength) are implemented;
TX-only methods return RigError::not_supported.  as_audio_source returns
None for now (overridden in SDR-07).  Wires the crate into the workspace
and trx-backend (feature "soapysdr"), and fixes the non-exhaustive match
on RigAccess::Sdr in trx-server main.rs and rig_task.rs.

sjg b00f054bd4 [feat](trx-server): add SdrConfig structs and SDR access config validation
Add SdrConfig, SdrGainConfig, and SdrChannelConfig structs to config.rs,
extend AccessConfig with an args field for the "sdr" access type, wire
SdrConfig into ServerConfig, and implement validate_sdr() with all
startup validation rules from SDR.md §11. Marks SDR-03 complete.

sjg b615b68e40 [feat](trx-core): add AudioSource trait and RigCat::as_audio_source
Add AudioSource trait to trx-core rig module providing subscribe_pcm()
for demodulated PCM audio. Add opt-in as_audio_source() default method
to RigCat returning None; SDR backends will override to return Some(self).
Re-export AudioSource from the crate root. Marks SDR-01 complete.

Add `RigAccess::Sdr { args: String }` to the backend access enum, register

handle the new variant in all existing `match` arms, and add the `soapysdr`
feature flag (no dep yet; implementation lands in SDR-04). Mark SDR-02 done.
