Note

Filters out hidden elements during content collection and schedules a delayed recheck after navigation events with cache invalidation.

• Page content collection:
  • Excludes hidden elements via checkNodeIsVisible in domToMarkdown.
  • Adds extra logging of collected markdown content.
• Navigation recheck:
  • Introduces delayed recheck timer (#delayedRecheckTimer) triggered on load, hashchange, and urlChanged.
  • scheduleDelayedRecheck() invalidates cache, recollects content, and sends response after a configurable delay (navigationRecheckDelayMs, default 1500ms).
  • Adds clearTimers() to cancel pending timers.
• Caching/observation:
  • Cache invalidation now paired with stopping observers; recheck path resets timers and observers appropriately.

Bug: Styling Checks Fail on Detached Nodes

The checkNodeIsVisible() function uses getComputedStyle() on cloned, disconnected DOM nodes. Since getComputedStyle() returns default values for disconnected elements, the visibility checks are unreliable, potentially filtering out visible content or including hidden content.

Going to split apart the PR into #1970 again. Then recheck the hidden part over coming back here.
