START: render transposed clips with Freeze/Flatten, TEMPO leader clips at their own tempo

Tested in Live on copies of 261101 (2026-10-26):
- Edit > Consolidate cannot be aimed at one clip from a script (no LOM selection; Edit > Select Loop
  selects every track, so Consolidate merged the SECTIONS markers and lighting cues). Each pitched track is
  now Freeze Track + Flatten Track (same audio: the stems have no devices), warp off, named like Consolidate
  names it; the Freeze tail clips and "(Freeze)" track names are removed. Groups unfolded to select, refolded.
- The TEMPO label clips lead the song tempo (IsSongTempoMaster): START renamed the base set's 143 clip
  without its warp markers, so Live played 261101 at 143 and consolidating rendered songs at the wrong
  length. lead_tempo() makes the markers match the BPM.
- AbletonOSC commands match Live's numbered/stamped track names; new refold and drop_tails commands.
- A run that stopped picks up flattened clips; START's look runs before the ROUTING/IN EARS reads.
