chore(release): bump to 0.27.0-fork.8 — auto-retry transient occlusion

fork.7 caught the X mask-overlay race correctly but reported it to
the user verbatim — every transient overlay (modal backdrop, focus
ring, click-outside mask, sticky banner) became an error the user
had to wrap in their own retry loop. Most of these clear within a
frame or two on their own.

Now `verify_click_target` retries the elementFromPoint probe a few
times (default 3 × 200ms = 600ms total grace period) before failing.
Real-world overlays that blink in for a render cycle clear during
the first retry; persistent overlays still surface as errors with
the same actionable message — just qualified with "still occluded
after N retries / Mms" so the user knows we tried.

Tunable:
  AGENT_BROWSER_OCCLUSION_RETRIES         (default 3, 0 disables)
  AGENT_BROWSER_OCCLUSION_RETRY_DELAY_MS  (default 200)

DOM.resolveNode is called once outside the loop — backendNodeId is
stable across renders, only the element under (x, y) changes when
overlays flicker. Each probe is still capped at 500ms so a stuck
Runtime.callFunctionOn can't stall a click for longer than the user
expects.
