### Fixes

- Control UI/Talk: make failed Talk startup errors dismissable and clear the stale Talk error state when dismissed, so missing realtime voice provider configuration does not leave a permanent chat banner. Fixes #77071. Thanks @ijoshdavis.

- Google Chat: create an isolated Google auth transport per auth client, so google-auth-library interceptor mutations do not accumulate across webhook verification and access-token clients. Thanks @vincentkoc.

- Control UI/performance: cap long-task and long-animation-frame diagnostics in the shared event log, so slow-render telemetry does not evict gateway/plugin events from the Debug and Overview views. Thanks @vincentkoc.

- Web fetch: late-bind `web_fetch` config and provider fallback metadata from the active runtime snapshot, matching `web_search` so long-lived tools do not use stale fetch provider settings. Thanks @vincentkoc.

- Discord: clear stale startup probe bot/application status when the async bot probe throws, not just when it returns a degraded probe result. Thanks @vincentkoc.
