pj fc1e6f9319 perf(web-runtime): cache randomTap candidate DOM scan per tick ...

The 16-attempt retry loop in __sanderlingNextAction__ called
randomTap repeatedly; each call ran querySelectorAll over a-button-
input-... and re-flushed layout per match via getBoundingClientRect.
On heavy SPA routes that's the per-tick budget gone.

Cache the scan in a module-level slot, reset at the top of each
__sanderlingNextAction__ invocation so the cache doesn't outlive a tick.
