KoalaDev ef1fdc89c3 test: prove the frame lifecycle fixes against the real extension ...

The evidence for the frame-observation fixes was a reimplementation of the
logic measured in a browser console, not the shipped code. Two extension
specs now cover the observable behaviour end to end: a player frame that
swaps its document, and the same one level deeper.

The nested case fails against the pre-fix content.js and passes now. The
top-level case already passed before the fix, so that fix removed dead
observer registrations without changing what a user could see; recorded
here so the distinction is not lost.

Also adds bench-finder.mjs, which measures the extracted shipped finder
instead of a transcription of it.
