Adds a per-rig meter broadcast channel on RigHandle and threads it
through run_rig_task. SDR meter tick drops from 100 ms to 33 ms; every
tick publishes a MeterUpdate while RigState is only updated on
>=0.25 dB deltas so rigctl/JSON-TCP frontends keep working without
amplifying state churn. Listener handles SubscribeMeter by converting
the TCP connection into a one-way JSON-line stream; TCP_NODELAY is
enabled on every accepted socket for low-latency frame delivery.

png::Writer::write_image_data only validates the total byte count,
so if individual scan lines were pushed at the wrong width the total
could still match and the resulting PNG would be silently skewed.
Explicitly check each row against pixels_per_line before encoding
and bail with a descriptive error if any row disagrees.
Also log the final file path, dimensions, and byte size at debug
level so corrupted-image reports have something concrete to look at.

Extend the between-poll meter refresh that was previously SDR-only
to also run on CAT backends. CAT rigs now poll the S-meter every
150 ms (SDR remains at 100 ms), so the frontend bar moves in near
real-time instead of updating only on the 500 ms full-state poll.
The fast path calls get_signal_strength_db() first (SDR), then
falls back to the coarse get_signal_strength() + map_signal_strength
path for CAT rigs. It is skipped while powered off, transmitting,
or while a full poll is paused after a CAT write.

When a bookmark switches to a mode that a currently-enabled toggle
decoder doesn't support (e.g. moving from DIG to FM while FT8 is on),
turn the incompatible decoder off. Previously bmApply only touched
decoders that were compatible with the new mode, leaving stale
decoders running against modulation they can't handle.
Compatible decoders keep their existing behaviour: if the bookmark
specifies a decoder set, toggles are driven to match it; otherwise
they're left as-is.

Relying on Drop to write the PNG IEND trailer and flush BufWriter
silently swallows I/O errors, which can leave truncated/corrupted
image files on disk. Explicitly call writer.finish() to surface
encoding errors and sync_all() the File so bytes are durable before
WefaxEvent::Complete is emitted with the path (the frontend may read
the file immediately). The intermediate BufWriter is dropped since
we already buffer all rows and write them in a single call.

Track sample-clock drift between transmitter and receiver by
cross-correlating each new scan line against the previous one at
shifts of ±6 samples. The best-matching shift nudges the slicer's
extraction cursor, keeping adjacent lines aligned and removing the
diagonal skew that would otherwise accumulate over an 800-line image.
A small correlation-peak deadband prefers d=0 on quiet lines, and a
minimum-variance guard skips flat reference lines where drift
estimation is meaningless. Enabled by default via
WefaxConfig::slant_correction.

PhasingDetector is strict (needs 10 phasing lines with low pulse-
position variance). On real-world signals with noise, tuning error,
or non-standard phasing, it can fail to converge — leaving the state
machine wedged in Phasing forever after a successful APT start
detection.
Add a ~30 s timeout: if phasing alignment doesn't lock after
PHASING_TIMEOUT_LINES worth of samples, fall through to Receiving
with phase_offset=0 and verified=false. The correlation verifier
then decides whether the content is real imagery (commit, eventually
save) or not (drop, back to Idle). The image will be horizontally
misaligned since we never locked phase, but it's better than a
stuck state that produces nothing.

Previously, the variance-based auto-start entered State::Receiving
directly and committed to saving whatever came out, relying on a
100-line minimum as a crude filter. This let any sustained tone or
noise burst allocate an image buffer and emit state events.
Replace that filter with real verification. Each entry into Receiving
is now tagged verified (phasing-driven) or unverified (variance
auto-start). Unverified receptions must produce 5 consecutive lines
of r >= 0.5 correlation within the first 40 lines to commit. Otherwise
the buffered content is dropped silently and the decoder returns to
Idle — no image saved, no history entry, no carrier-lost event.
The carrier-loss watchdog is now gated on verified==true so it can
only ever finalize genuine captures. Phasing-driven receptions (APT
start tone + phasing pulses) enter verified and don't wait on the
correlation streak.
The 100-line minimum in finalize_image is removed — verification is
a cleaner semantic gate. A very short but genuinely phasing-validated
capture will now save.

The variance-based auto-start in Idle state is permissive and fires on
any sustained modulated audio — tones, beeps, noise bursts. When that
happens mid-transmission, the decoder enters Receiving, the correlation
watchdog trips after exactly 31 lines (1 seed + 30 low-correlation),
and we end up saving a sliver of garbage to disk and the history.
Gate finalize_image() on a 100-line minimum. A real WEFAX chart is
hundreds of lines; anything shorter is almost certainly a false
auto-start and gets dropped silently (with a debug log). This doesn't
change start-tone / phasing-driven captures, only filters out the
noise-triggered entries.

WEFAX images were only saved to disk and recorded in history when an APT
stop tone was detected or the decoder was explicitly reset. If the
transmission broke (carrier dropout, tuning drift, noise masking the
stop tone), the decoder stayed in Receiving state forever and the
partial image was never flushed.
Add a line-to-line Pearson correlation watchdog modelled on fldigi's
wefax automatic stop: real imagery has highly correlated adjacent scan
lines, while noise does not. After 30 consecutive low-correlation lines
(~15s at 120 LPM, ~30s at 60 LPM) the decoder finalizes the image,
emits WefaxEvent::Complete, and returns to Idle — so partial
transmissions show up in the web UI history like completed ones.
Flat lines with near-zero variance are treated as "undefined" and
leave the counter unchanged, so solid black/white image bands don't
falsely reset or trip the watchdog.

Dynamic scripts (map-core.js etc.) are effectively async and can execute
before the defer'd app.js that creates window.trx. When map-core.js is
served from browser cache it loads instantly and crashes on
`const T = window.trx` (undefined), preventing window.trx.map from
ever being set — the map never initialises and Ctrl+R is needed.
Move eager plugin loading from the inline script to app.js, triggered
via window.loadEagerPlugins() after window.trx is fully populated.
This guarantees the namespace exists before any plugin script runs.

APT start/stop signals are not audio-frequency tones — they are
black↔white transition rates in the FM-demodulated output (300, 675,
450 transitions/s). The Goertzel detector was running on the raw ~1900 Hz
carrier where no energy exists at those frequencies, so APT detection
never fired on real HF WEFAX signals.

luminance (matching fldigi's decode_apt), and swap the processing order
so FM demodulation runs before APT detection.
