    syncretro: band-align dirty rects for cell-anchored terminals

    Add a band_align option to sr_dirty_find(): snap each rect height to LCM(cell_h, 6) -- a whole number of both text cells and 6px sixel bands
    -- and fall back to a full frame if a bottom-clamped rect can't cover
    its own changed rows. This is the discipline termgfx's SCUMM dirty path
    already carries to keep foot from backfilling a partial trailing band as
    a black strip. Passed 0 for now (SyncTERM path unchanged, byte-for-byte)
    so the correctness machinery lands before the non-SyncTERM gate opens.
