E2E Test Selection:
The changes are in WalletConnectV2.ts (removeAll method) and its test file. The core change adds permissionsController.revokeAllPermissions(session.pairingTopic) before disconnecting each WalletConnect session during a full session removal. This is a correctness fix ensuring permissions are cleaned up when WC sessions are removed.

Key observations:

1. No dedicated WalletConnect E2E smoke tests exist in the test suite (confirmed by searching tests/smoke/ and tests/regression/).
2. The change touches the PermissionController interaction, which is relevant to dApp chain permissions and session management.
3. SmokeNetworkAbstractions covers chain permission system for dApps (granting/revoking chain access) — directly relevant since this change affects permission revocation during WC session cleanup.
4. SmokeMultiChainAPI covers CAIP-25 multi-chain session API and wallet_revokeSession — directly relevant since this change ensures permissions are properly revoked when sessions end.
5. The change is wrapped in try/catch so it's non-breaking if PermissionController throws.
6. No UI changes, no performance-sensitive paths affected.

The selected tags cover the dApp permission and session management flows most likely to be affected by this change.

Performance Test Selection:
The change only adds a permission revocation call (revokeAllPermissions) in the WalletConnect removeAll() method. This is a cleanup operation that runs when all WC sessions are removed — not in any hot path, rendering loop, or performance-sensitive flow. No performance tests are warranted.
