Add SpectrumData struct (bins, center_hz, sample_rate) to RigState and
RigSnapshot. Add GetSpectrum RigCommand and ClientCommand plumbed through
the protocol layer. SoapySDR DSP pipeline now computes a 1024-bin FFT
(Hann window, FFT-shifted, dBFS) every 4 IQ blocks (~10 Hz update rate)
and exposes it via RigCat::get_spectrum(). The rig_task handles
GetSpectrum without persisting spectrum data in ongoing state.

Include optional display_name field in GetRigs response to allow clients
to show friendly rig names instead of just identifiers.

Improve assertion and struct literal formatting across test cases
for better code clarity and consistency.

Add SetBandwidth { bandwidth_hz: u32 } and SetFirTaps { taps: u32 } to
ClientCommand with bidirectional mapping to RigCommand variants.
Add UC-09 protocol serialization tests confirming that RigSnapshot
serializes the filter field when Some and omits it when None.

Add GetRigs command, rig_id routing fields, and RigEntry type:
- ClientCommand::GetRigs (intercepted in listener before rig_task)
- rig_id: Option<String> on ClientEnvelope (absent = first rig)
- rig_id: Option<String> and rigs: Option<Vec<RigEntry>> on ClientResponse
- RigEntry { rig_id, state } for GetRigs aggregated response
- Sentinel unreachable!() arm for GetRigs in client_command_to_rig()
- MR-09 codec tests: rig_id parsing, GetRigs round-trip, serde omit-when-None
