Estimate Co-Channel Interference (CCI) from pilot tone quadrature
leakage and coherence degradation. Estimate Adjacent Channel
Interference (ACI) from CMA equalizer tap deviation from identity.
Both metrics (0-100 scale) are surfaced through RigFilterState and
displayed as colour-coded bars in the WFM control panel.
The RDS decoder quality parameter is now adaptively penalised when
CCI/ACI levels are elevated, reducing block-error rate under
interference conditions.

The map module was tagging all decode markers (APRS, AIS, VDES,
FT8/FT4/FT2/WSPR locators) with the global rig picker's active rig
instead of the actual source rig. This made the map's own rig filter
dropdown ineffective in multi-rig setups.
- Add rig_id field to all decode message structs (AisMessage,
VdesMessage, AprsPacket, CwEvent, Ft8Message, WsprMessage)
- Set rig_id on messages in audio_client before broadcasting, using
the actual rig connection identifier
- Update history collector to prefer message rig_id over the global
active rig fallback
- Pass rig_id through plugin normalize functions (AIS, APRS, VDES,
HF-APRS) so it reaches the map add functions
- Update all map marker functions (aprsMapAddStation, aisMapAddVessel,
vdesMapAddPoint, mapAddLocator) to use the message's rig_id with
fallback to the global picker for backward compatibility

Extract 13 SDR-specific methods (set_center_freq, set_bandwidth,
set_sdr_gain/lna/agc/squelch/nb, set_wfm_*, filter_state, get_spectrum,
get_vchan_rds) into a new RigSdr trait. RigCat retains core CAT
operations and gains as_sdr()/as_sdr_ref() for optional SDR access.
Non-SDR backends no longer see SDR methods in their trait impl.

Add hardware AGC on/off control for SoapySDR backend, wired through the
full stack from RigCommand to the web UI:
- RigCommand::SetSdrAgc(bool) + ClientCommand::SetSdrAgc in protocol
- set_sdr_agc() on RigCat trait (not-supported default)
- SoapySdrRig: agc_enabled field, set_sdr_agc() via pipeline agc_cmd,
sdr_agc_enabled in filter_state(); removes the "not yet implemented"
warning — gain_mode="auto" now properly enables hardware AGC via
SoapySDR set_gain_mode()
- IqSource::set_gain_mode() trait method; RealIqSource implements it
- SdrPipeline: agc_cmd channel, read loop applies it each iteration
- POST /set_sdr_agc endpoint in trx-frontend-http
- New "SDR settings" full-row in index.html with Hardware AGC checkbox
and RF Gain (moved out of WFM controls); row hidden when
show_sdr_gain_control is false

syncs checkbox state from filter.sdr_agc_enabled

Allow users to allocate multiple virtual channels independently of
browser tab count. Channels survive SDR center-frequency retuning as
long as they stay within the capture bandwidth; channels that fall
outside the SDR span are automatically destroyed.
Changes:
- trx-core: add AUDIO_MSG_VCHAN_DESTROYED (0x12) wire constant;
add default subscribe_destroyed() to VirtualChannelManager trait
- trx-backend-soapysdr: update_center_hz() detects OOB channels,
removes them, fires destroyed_tx broadcast; add destroyed_sender()
and subscribe_destroyed() override
- trx-server/audio: recv_destroyed() helper avoids select! busy-loop
for non-SDR backends; send AUDIO_MSG_VCHAN_DESTROYED to client when
a channel is evicted server-side
- trx-client/audio_client: persist active_subs across TCP reconnects,
re-subscribe on reconnect; handle AUDIO_MSG_VCHAN_DESTROYED by
pruning vchan_audio map and forwarding UUID via vchan_destroyed_tx
- trx-frontend/lib: add vchan_destroyed broadcast field to
FrontendRuntimeContext
- trx-client/main: wire vchan_destroyed_tx into audio client and
frontend runtime context
- trx-frontend-http/vchan: remove per-session one-channel limit in
allocate(); replace auto-evict in release_session_on_rig() with
subscriber-count-only update; add remove_by_uuid() for server-
triggered OOB destruction (skips redundant VChanAudioCmd::Remove)
- trx-frontend-http/server: spawn background task that forwards
vchan_destroyed broadcast to ClientChannelManager.remove_by_uuid()

Add VirtualChannelManager trait in trx-core::vchan with types VChannelInfo,
VChanError, and SharedVChanManager alias. Re-export from trx-backend::vchan.
Implement SdrVirtualChannelManager in trx-backend-soapysdr:
- Wraps Arc<SdrPipeline> + shared AtomicI64 center_hz
- add_channel / remove_channel / set_channel_freq / set_channel_mode
- Slot-stability: on remove, shifts pipeline_slot for surviving channels
- update_center_hz: recomputes IF offsets for all virtual channels on retune
- update_primary_meta: keeps channel-0 freq/mode in sync for API consumers
Wire into SoapySdrRig (holds Arc<SdrVirtualChannelManager>, exposes
channel_manager()), SdrPipeline (shared_center_hz AtomicI64), and RigHandle
(vchan_manager: Option<SharedVChanManager>). main.rs extracts the manager
before boxing the SDR rig and stores it in the handle.
Add max_virtual_channels to SdrConfig (default 4, TOML-configurable).
Add 5 unit tests: add, remove, permanent guard, cap, out-of-bandwidth.

State deduplication via PartialEq + send_if_modified:
Derive PartialEq on the full RigState / RigSnapshot type tree
(Freq, Band, RigInfo, RigCapabilities, RigStatus, RigTxStatus,
RigRxStatus, RigControl, RigVfo, RigVfoEntry, RigFilterState,
RdsData, SpectrumData, RigState, RigSnapshot). Use
state_tx.send_if_modified() in refresh_remote_snapshot() so
WatchStream only wakes SSE /events subscribers when state
actually changed; with a stable rig this eliminates ~1.3
spurious JSON serialisations per second per connected client.
Cache-remote-rigs skip on unchanged list:
cache_remote_rigs() was rebuilding the Vec and cloning every
field on every 750 ms poll. Add a structural check (rig_id,
display_name, initialized, audio_port) and return early when
nothing has changed — the common steady-state case.
RDS JSON pre-serialised at ingestion:
SharedSpectrum.replace() now serialises the optional RDS object
once and stores it alongside the Arc<SpectrumData> frame.
Each /spectrum SSE client's 40 ms tick reads the cached string
instead of calling serde_json::to_string() per-client per-tick.
Add serde_json to trx-frontend Cargo.toml to support this.

Add flate2 dependency and a new AUDIO_MSG_HISTORY_COMPRESSED (0x0a)
wire type. The server gzip-compresses the full history blob before
sending; JSON history compresses ~10-20x so both transfer size and
client wait time drop significantly. The client decompresses and
dispatches sub-messages from the embedded framed stream. MAX_PAYLOAD_SIZE
is kept at 1 MB for normal messages; a separate 16 MB limit is applied
only to the compressed history type.
