- Return an unchanged copy for a non-finite/zero grid (NaN downbeat used to
delete every guitar note).
- Skip an added note when a same-pitch note (bar, neighbouring bars or already
added) lies within tol; avoids near-duplicates across bar lines.
- bench run/real: --no-repeat-vote passes { repeatVote: false } to the pipeline.
- Tests: notes before a late downbeat, bpm 0 / NaN / Infinity, trailing partial
bar, half-tempo grid, neighbour-bar duplicate, pipeline-level on/off.
Eval unchanged: synthetic t1a 0.885 t1b 0.840 t1c 0.752 t1d 0.737, lnoe 0.507.

Bars whose transcriptions are similar (16th-slot occupancy cosine >= 0.6,
diagonal-smoothed, and exact pitch/onset match >= 0.3) are treated as repeats.
Notes recurring in < 15% of a bar's repeats are dropped; notes in >= 25% and
>= 3 repeats but missing from the bar are added. Default on for guitar.
