Add RealIqSource that connects to actual SoapySDR devices when soapysdr-sys
feature is enabled. Implements proper device initialization, frequency/bandwidth
configuration, gain control, and RX stream management.
When soapysdr-sys feature is disabled (default), falls back to MockIqSource
for testing. Update feature flags in Cargo.toml dependencies to support both
real hardware and mock operation.
- Device initialization with proper error handling
- RX frequency, bandwidth, and gain configuration
- IQ sample streaming via broadcast channel
- Proper resource cleanup via Drop trait
- Throttled MockIqSource to prevent 100% CPU

Add sleep proportional to block duration in iq_read_loop to simulate
real hardware timing. MockIqSource immediately returns samples without
any delay, causing busy-looping. Throttling prevents excessive CPU usage
when using the mock source.

Fix useless vec! allocation in demod tests, improve loop iterator usage,
and reformat code for better readability across dummy and soapysdr
backends.

Set tx/tx_limit/vfo_switch/filter_controls/signal_meter on all backends:
- FT-817, FT-450D, dummy: tx=true, tx_limit=true, vfo_switch=true,
filter_controls=false, signal_meter=true
- SoapySDR: tx=false, tx_limit=false, vfo_switch=false,
filter_controls=true, signal_meter=true
SoapySDR backend now stores bandwidth_hz and fir_taps fields; overrides
set_bandwidth, set_fir_taps, and filter_state on RigCat to expose live
DSP state in the snapshot.
Add UC-08 unit tests on dummy backend asserting tx capabilities present
and filter_controls absent, and that filter_state returns None.

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.

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.

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.

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.

Add `RigAccess::Sdr { args: String }` to the backend access enum, register
a feature-gated `soapysdr` factory stub in `register_builtin_backends_on`,
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.

Replace legacy global BackendRegistry with bootstrap context adapter that
maintains backward compatibility while delegating to explicit context.
Changes:
- Create BOOTSTRAP_CONTEXT: OnceLock<Arc<Mutex<RegistrationContext>>>
- register_backend(): delegates to bootstrap context
- is_backend_registered(): reads from bootstrap context
- registered_backends(): reads from bootstrap context
- build_rig(): reads from bootstrap context
Result: Plugins continue calling global functions, but all operations
now route through the bootstrap context instead of a separate global
registry. This completes the de-globalization while maintaining full
backward compatibility with existing plugins.

Add register_builtin_backends_on(context: &mut RegistrationContext) function
to allow explicit backend registration on a context instead of always using globals.
This enables proper initialization sequencing where backends are registered
on a specific context that can be passed through bootstrap.
The global register_builtin_backends() still works for plugin compatibility,
delegating to the new context-based approach.

Create explicit RegistrationContext type for backend factory registration
instead of relying solely on global mutable state.
New RegistrationContext:
- register_backend(name, factory) - register a backend
- is_backend_registered(name) - check if registered
- registered_backends() -> Vec<String> - list all backends
- build_rig(name, access) -> DynResult - instantiate a rig
Maintains global API for plugin compatibility, delegates to context.
Paves way for threading context through bootstrap in Phase 3B.

Move the frontend and backend crate trees to live physically under their
respective binary crate directories, grouping related code together
without merging crate boundaries. Also flatten sub-crate nesting by
moving them out of src/ subdirectories into direct children.
