Add fold/unfold of JSON objects and arrays in console command results, built on
the refactored channel + model foundation.
- ComputeConsoleFoldSpans() (console_input_model): pure brace/bracket matcher
over a block of pretty-printed JSON lines; each opener line gets the offset to
its matching closer at the same indentation (empty/one-line blocks are not
foldable). Unit tested (nested objects, arrays, empty blocks, non-JSON, and a
string value that merely contains a brace).
- ConsoleModelLine gains foldSpan (relative, so it survives front-eviction by the
line cap) + a collapsed flag; ingest() carries the span and toggleCollapsed()
flips openers (main thread). addFormattedResult computes the block's spans and
ingests them atomically.
- computeVisibleLines() skips a collapsed block's interior (opener stays, its
foldSpan lines through the closer are hidden); folding is bypassed while a
filter is active so every match stays reachable.
- drawVisibleLines() draws a fold triangle in the free left gutter of opener
lines (result/JSON channels carry no accent bar there), toggled by a click in
the gutter cell, and appends a dim " ... }" / " ... ]" summary on collapsed
openers.
Full-node + lite build clean; ctest green (incl. fold-span + model-fold tests);
source hygiene clean.
