Patch Changes

• #​3191 9f41d26 Thanks @​TueHaulund! - fix(replay): fall back to persisted config when remote config fetch fails

  When the remote config fetch failed (network error, ad blocker, CDN outage), the SDK received an empty {} response with no sessionRecording key. The onRemoteConfig handler returned early without ever setting _receivedFlags = true, leaving the recording permanently stuck in pending_config status for the entire page session.

  This removes the _receivedFlags gate entirely. The 1-hour TTL on persisted config (added in #​3051, increased from 5 minutes) and the stale-config retry in _onScriptLoaded (added in #​3093) already prevent recording from starting with outdated config. The additional gate was redundant and created a deadlock when the config fetch failed.

  Now when the config fetch fails, startIfEnabledOrStop() is called and falls back to persisted config from a previous page load. If no persisted config exists (first-ever visit), recording is correctly disabled rather than silently stuck. (2026-03-04)

• #​3198 9d0df0e Thanks @​TueHaulund! - Reduce session replay memory pressure by tracking per-event sizes in SnapshotBuffer, eliminating redundant JSON.stringify calls during buffer operations. Also bumps @​posthog/rrweb to 0.0.46 which uses FNV-1a hash-based canvas frame deduplication instead of storing full base64 strings.
