* feat(analytics): capture JS exceptions to PostHog Turn on posthog-js exception autocapture (window.onerror + unhandled rejections, with stack) and add a buffered captureException() wrapper for boundary-caught React errors those handlers can't see. Wire the web route-level global-error boundary to report through it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(diagnostics): add shared freeze watchdog Long-task observer (>=2s) emits client_unresponsive via captureEvent; client_type super-property tags desktop vs web for free. Installed once in CoreProvider so web and desktop share one in-thread, SSR-safe detector for recoverable freezes.

The main process now persists a breadcrumb on unresponsive / render-process-gone, and the next renderer boot flushes it to PostHog (client_unresponsive / client_crash). A recovered hang clears its breadcrumb so it isn't double-counted by the in-thread watchdog.

Add a before_send hook that redacts emails, URL query strings, and long opaque tokens from the exception message and $exception_list values, keeping type + stack frames (code locations, not user data). Addresses the privacy gap from leaving capture_exceptions on with no sanitizer.

Cover: hang->write, recover->clear (no double-count), recover-before-delay->no-op, force-quit->retained, crash->write-and-never- clear, clean-exit->no-write. Add watchdog tests (threshold, idempotent, SSR/PerformanceObserver no-op) via a fake observer.

Document why preload-error skips the breadcrumb and the single-slot last-write-wins undercount limitation.
