The Electron suites were only reachable one npm script at a time, so a new
one was covered by whoever remembered it existed. test:electron:all builds
once and runs all five, reporting a single summary and a non-zero exit.
The runner lives under tests/ rather than app/scripts/, which .gitignore
excludes entirely.
The image row spacing assertion also stops hard-coding the current gap --
it had 0.59px of headroom -- and calibrates against the spacing the rest of
the timeline is using.

The wide-image probe resolved only from a load handler that a regression
could keep from ever firing, and it was awaited bare, so a broken build
hung the run instead of reporting a failure. Every renderer probe now runs
against a deadline, the probe rejects on image error, and the suite as a
whole is bounded.
Adds a held image endpoint so an above-viewport image can be made to finish
at a moment the test controls, and asserts the reader does not move -- both
at rest and mid-gesture, which is where it regressed.
