v2.201.0 — E149: a rename is inferred from overlapping windows

Added

• A rename is inferred from overlapping windows when the only cut of a
  source was re-centred. Alias inference demanded an identical record
  window under two names, so a source with a single cut sitting inside a
  re-centred dissolve could never be aliased: it read as gone plus new
  plus a dropped and an added dissolve — three such junctions on a real reel.
  A second tier now adopts a rename from unpaired cuts on the same track
  whose windows overlap under clearly-the-same names (LCS similarity ≥ 0.8),
  reported with byOverlap. A different shot in an overlapping window stays
  a replacement. On the reel: the three phantom drop/add pairs are gone, the
  cuts pair, and one of the junctions folds outright.
