MARINE was a composite mode that ran both AIS and VDES decoders
simultaneously. It is now fully replaced by allocating two virtual
channels — one tuned to the AIS frequencies and one to VDES — each
decoded independently.
- trx-core/state: remove RigMode::MARINE variant
- trx-protocol/codec: remove MARINE parse/serialize
- trx-backend-ft817: remove MARINE from unsupported-mode guard
- trx-backend-ft450d: remove MARINE from FM CAT code mapping
- trx-backend-soapysdr: remove MARINE from bandwidth table, supported
modes list, AIS channel activity check, parse_rig_mode, vchan_impl
bandwidth table, demod selection, dsp/channel bandwidth / sample-rate
/ IQ-tap guards
- trx-server/audio: remove MARINE from AIS and VDES decoder activation
- trx-server/rig_task: remove MARINE from audio-streaming mode list
- trx-server/main: remove MARINE from bandwidth table, mode parser,
VDES channel subscription match
- app.js: remove isMarineMode(), MARINE entry in MODE_BW_SPECS, MARINE
bandwidth specs block in visibleBandwidthSpecs(), MARINE from
decoder status mode lists, MARINE BW-edge drag guard

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.

Replace the fixed channel_dsps Vec (thread-owned) with an
Arc<RwLock<Vec<...>>> shared between the IQ read thread and the async
side, enabling live add/remove of virtual DSP channels.
Cache audio construction params in SdrPipeline so add_virtual_channel()
can build ChannelDsp instances without being re-passed them. Add:
- SdrPipeline::add_virtual_channel() / remove_virtual_channel()
- SoapySdrRig::virtual_channel_add/remove/set_freq/set_mode()
- SoapySdrRig::center_hz() / half_span_hz() accessors
The IQ read loop holds a brief read lock (~2 ms per block) while
processing all channels; write lock for add/remove waits at most one
block. All 27 existing tests continue to pass.

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.

Assigns message type 0x09 to HF APRS decoded frames on the binary
audio TCP channel and wires it up in all three layers:
- trx-core: AUDIO_MSG_HF_APRS_DECODE = 0x09
- trx-server: emit 0x09 in the live dispatch match and include
hf_aprs history in the connection-open replay blob
- trx-client: recognise 0x09 and forward to the decode broadcast

Replace per-message write + flush-every-64 with a single in-memory blob
that is sent via one write_all + one flush. Add estimated_total_count()
to DecoderHistories for pre-allocation. Eliminates N/64 partial flushes

histories.

Subscribe to the first sdr.channels[] entry configured as VDES or
MARINE instead of always using channel 0. The ChannelDsp IQ tap only
emits samples when its own mode is VDES/MARINE, so the two must agree.
Fix vdes_sr to mirror channel.rs pipeline_rates(): use
audio_sample_rate.max(96_000) as the target rather than the hardcoded
96_000. The two diverge when audio_sample_rate > 96_000, causing the
VdesDecoder to use the wrong symbol-to-sample ratio.

Move persistent history from trx-client to trx-server where decode
events originate. History for AIS, VDES, APRS, CW, FT8, and WSPR is
loaded from ~/.local/cache/trx-rs/history.db at startup and flushed
to disk every 60 seconds. CW events are now also stored in
DecoderHistories and replayed to connecting clients, consistent with
all other decoder types.

Two problems prevented reliable recovery after a persistent overflow:
1. Restart storm: once read_error_streak >= 3, every subsequent read
failure triggered a deactivate/activate cycle, potentially preventing
the hardware from stabilising. Fix: after a successful restart, reset
read_error_streak to 1 so the stream gets 2 more failures before the
next restart attempt.
2. Stuck-deactivated stream: if activate() failed after overflow, the
stream was left deactivated. Subsequent reads returned non-overflow
errors which handle_read_error ignored (Ok(false)), so the stream was
never reactivated. Fix: add a high-streak fallback (>= 10 consecutive
errors of any kind) that also attempts a full deactivate/activate
restart, covering the stuck-deactivated case.

Two bugs triggered by a SoapySDR IQ overflow:
1. Spectrum dies permanently (trx-client): when GetSpectrum times out
(300ms SPECTRUM_IO_TIMEOUT), the error was silently swallowed and
the spectrum buffer cleared. The in-flight response remained in the
TCP receive buffer, desynchronising all subsequent reads so every
poll kept failing. Fix: propagate the error so handle_connection
returns and the outer loop reconnects, restoring TCP sync.
2. CTRL+C hangs trx-server: after IQ overflow, the sdr-iq-read thread
can get stuck in a blocking SoapySDR/USB call (deactivate/activate
with no timeout). Tokio received SIGINT and aborted async tasks, but
the process could not exit while the native thread was blocked in
uninterruptible I/O. Fix: call std::process::exit(0) after the
graceful shutdown sequence so the OS forcibly terminates all threads.
