#1188 perf(web): wheel a node already under aim without hovering it

What and why

• An element swipe used to hover() before every wheel: an actionability wait and a pointer move, every scrollUntilVisible stride.
• Now one page-side read (wheelAim in packages/web/src/support.ts) picks the path:
  • pointer: the node is already :hover, so it wheels where the pointer is.
  • centre: the hit target at the node's centre is inside it, so it moves there and wheels.
  • blocked (covered, off screen, in an iframe): hover() as before, so actionability errors are unchanged.

Verified

Ran it locally: yes

• apps/web-benchmark, e2e run --workers 1, 2 runs each. All 91 tests pass.
