LIGHT TIMING: the real offset up to a full 16th, no flag on a cue already on a solid hit, hold moves the cues

- Detection in 2.5 ms steps; where a hit starts is halfway up its rise; each song's cues on solid hits set its "on time"; a cue already on a solid hit is never named; "about a 16th" when it is - Hold: moves the off cues onto their hit in the open set through a status panel command added to AbletonOSC (tools/abletonosc), keeping each cue's end; the key asks for a save until the set is saved Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

+/live/statuspanel/move_note <track name> <beat> <pitch> <new beat>
+    Moves the note of `pitch` that starts at arrangement `beat` on the arrangement MIDI clip of the track
+    called `track name` so it starts at `new beat`, keeping where it ends (the next cue is not touched).
+    Answers (<track name>, <beat>, <pitch>, <moved: 0 or 1>). Undo in Live (Cmd+Z) puts it back.
