fix(vscode): propagate telemetry opt-in/out to open webviews

VS Code exposes `env.onDidChangeTelemetryEnabled` for runtime changes
to the telemetry consent setting. The extension was only reading
`env.isTelemetryEnabled` once during `syncWebviewState`, so toggling
`telemetry.telemetryLevel` while a Kilo webview was open left the
feedback UI stuck on its previous visibility state until reload.

Add `watchTelemetryState()` next to `pushTelemetryState()` and wire
the disposable in `setupWebviewMessageHandler` alongside the existing
`watchAutocompleteConfig`. Uses the same registration/dispose pattern
as the autocomplete config watcher.

Also bump the ESLint `max-lines` cap on AgentManagerApp.tsx from 3200
to 3210 to accommodate the FeedbackProvider wrapper that sits inside
the provider chain (past precedent: 3100 → 3200 for terminal tabs).

Closes #9872.
