Add Auto checkboxes (checked by default) next to WPM and Tone inputs.
Auto Tone uses a multi-bin Goertzel scan across 300-1200 Hz with
stability tracking. Auto WPM collects on-durations in a rolling buffer
and uses k-means-style clustering to separate dits from dahs.
Unchecking Auto allows manual control.

Fix three bugs in the Bell 202 AFSK demodulator preventing frame
decoding:
- Separate NRZI state from clock recovery (shared lastBit variable
caused NRZI to always output 1)
- Buffer 1-bits in ones counter instead of pushing to frameBits
immediately, preventing flag/stuff bits from contaminating frame
data and corrupting byte alignment
- Detect flags via ones-count on decoded bits instead of shift
register on raw bits
Also add framed packet log container styling, remove redundant
description text, and add debug counters logging pipeline health

Replace #[tokio::main] with a manual fn main() that builds the tokio
runtime explicitly. All async initialization moves into async_init().
When the appkit frontend is requested, the runtime context is entered
