OnMic — what's new

- Moved Sign out from the top account bar to the bottom footer next to Copy
  support bundle, while keeping the confirmation dialog.

- Flatten now first tries to gather the kept camera video pieces onto one real
  top video track after cutting/deleting unused pieces. It only accepts that
  result if Premiere verifies the top track has the expected pieces.
- If Premiere will not safely verify the one-track copy, Flatten falls back to
  the proven top nested video clip from v0.70 instead of guessing.
- Standard Apply now adjusts batch size while it runs: faster batches can grow,
  slow batches shrink, and the timing log separates Premiere/panel overhead.

- Flatten no longer locks or unlocks any audio tracks while creating the top
  nested video result. It still only selects, cuts, removes, and clears camera
  video pieces, leaving existing audio tracks alone.

- Reworked Flatten again to use Premiere's own nested-sequence workflow for the
  finished top video item, instead of rebuilding hundreds of clips from raw
  project media.
- Flatten now only reports success if Premiere creates and places one top nested
  video clip, then clears the lower duplicate camera pieces.

- Flatten now finishes by placing the surviving camera pieces onto one new top
  video track, then clearing the lower-track duplicates. Audio tracks are still
  untouched.
- If Premiere cannot place every piece onto that top track, OnMic leaves the
  original kept pieces in place and tells you to restore the backup instead of
  pretending the flatten succeeded.
- Wide-shot Frequency "Low" is nudged slightly higher again, while staying below
  Medium.

- Shortened the Output dropdown label back to "Flatten" so Premiere's CEP
  dropdown reliably shows it as a selectable option.
- Kept the stronger Flatten explanation in the preview/apply confirmation text
  instead of cramming it into the dropdown itself.

- Reworked Flatten so it no longer rebuilds clips from raw source media. It now
  cuts the existing camera video clips and removes the unused camera pieces,
  preserving the actual timeline clips, timing, transforms, and effects.
- Audio tracks are locked while Flatten removes unused camera pieces, then their
  previous lock state is restored.
- The Flatten option and confirmation text now say what it really does: delete
  unused camera pieces, not create a rebuilt top-track copy.

- Standard Apply now repaints in fewer, larger waves. Long episodes should spend
  less time pausing between batches, with the tradeoff that the progress bar
  updates less often.
- Cleaned up the Apply timing log so direct clip visibility does not get reported
  as a scary "batch fallback" when Premiere simply has no safe batch command.
- Flatten now places clips at Premiere tick times instead of raw seconds, while
  still restoring each source in/out immediately after every placed segment.
