• #2834 548b466 Thanks @ordehi! - fix: Clear PageViewManager state on session rotation to prevent cross-session duration pollution

  When a browser tab is backgrounded and the session rotates (30 min idle or 24 hour max), PageViewManager now clears its state. This prevents $prev_pageview_duration from spanning session boundaries, which was causing impossibly large values (94+ hours observed) in web analytics "Average Time on Page" metrics.

  Users who implemented workarounds for inflated $prev_pageview_duration values (e.g., capping at 30 minutes) may want to review those after upgrading, as the root cause is now fixed. (2025-12-31)
