OnMic — what's new

- Added warning-only sync checks to Check sequence. OnMic now flags suspicious
  mic/camera start or end mismatches before analyzing or cutting.
- Removed the confusing "speaker order matches track order" checklist reminder.
- Removed the unfinished Find show start beta from Advanced.
- Kept OnMic's normal non-destructive editing flow unchanged.

- Made Speaker Names and Tag Speakers rows use the same label-and-box layout
  as the Layout controls.
- Speaker name boxes and Select Speakers boxes now share the same width and
  right-side alignment.

- Made the speaker-name boxes line up with the camera tag boxes below them.
- Removed the small mic-channel labels next to speaker names so setup reads
  cleaner and less technical.

- Renamed "Cutting Method" to "Edit Pace" so the setting reads more like an
  editing style choice.
- Renamed the pace choices to Balanced, Quick Cuts, and Relaxed.
- Moved Edit Pace into Advanced so the main setup stays simpler.

- Removed the visible Flatten choice from Advanced while we keep the real
  one-track Flatten problem on the back burner.
- OnMic now always applies the normal non-destructive switching path, even if
  an older saved setup/profile still had Flatten saved.
- Cleaned up sequence-check wording so the panel no longer points users toward
  Flatten while the option is hidden.

- Flatten is still available, but it no longer uses macOS/Windows shortcut
  automation to move clips between tracks.
- Flatten now only uses a direct Premiere command if Premiere exposes one to
  extensions. If that command is hidden, OnMic stops before changing the
  timeline and tells you to use non-destructive switching for that sequence.

- Fixed the new panel-driven Flatten path stopping at "selection-mismatch" by
  verifying selected video pieces by clip identity/timing instead of fragile
  JavaScript object identity.
- The Flatten shortcut path now rejects any selected audio item explicitly and
  refreshes Premiere's timeline selection before sending the move-up shortcut.

- Fixed the previous Flatten shortcut attempt being placed in the Premiere host
  script, where this Premiere copy does not expose system-command automation.
- Flatten now prepares/selects the existing cut timeline pieces in the host,
  sends Premiere's move-up-track shortcut from the CEP panel's Node layer, then
  returns to the host to verify the top track before deleting unused camera
  pieces. This is still a test path and still leaves audio untouched.
