Replaces the all-or-nothing "Errors only" collapse with a contextual
fold: ±25 entries around every error stay visible, and runs of
non-error entries with no nearby error collapse into a fold bar.
Each fold bar is draggable. Vertical pointer drag on the bar reveals
or re-hides lines from the top of the hidden range, ~6 px per line.
A click without drag reveals the next 25 lines. When the run is
fully revealed, the bar removes itself. Buttons / scroll behaviour
are unchanged; the existing "X errors" toggle in the header is the
entry point and still un-collapses everything on second click.
Visual: foldable bars get a faint horizontal hatch (suggesting
compressed content), an ns-resize cursor, and a hover/dragging
state that intensifies the hatch toward --accent. The grip-lines
icon flanks the line-count to call out the affordance.
