* feat(studio): add resolver-shadow attempt counter for soak-gate denominator Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(studio): harden attempt-counter exception safety and tab-hide flush ordering PR review feedback (4 reviewers): recordAttempt() sat outside the try/catch in all three emit functions, so a throw inside it (e.g. setInterval/ addEventListener failing in a non-standard environment) would break the "never throws" contract. Also, the new visibilitychange listener races studioTelemetry.ts's own tab-hide handler — whichever fires first can beacon the queue before or after this module's rollup lands in it, silently dropping the attempt count for short sessions closed before the 5-minute timer fires. Fixes: move recordAttempt() inside each function's try block; export flushViaBeacon() from studioTelemetry.ts and call it explicitly after queuing the rollup, so delivery no longer depends on listener registration order; capture the visibilitychange handler by reference so __resetAttemptSchedulingForTests() actually removes it instead of leaking a duplicate on re-arm.
