Support console.clear in playground

[justonemorenight]

Summary

• forward console.clear() calls from the playground iframe
• clear the parent playground log output when the message is received
• extend the playground message type with a clear event

Fixes #1578

Validation

• pnpm build
• cd website && pnpm lint
• cd website && pnpm build.types
• cd website && pnpm exec prettier --check src/routes/playground/iframeCode.js src/routes/playground/index.tsx

Summary by CodeRabbit

• Bug Fixes
  • The playground’s clear-console command now correctly clears captured log output.
  • Console clearing in the playground no longer affects the parent page’s console.
  • The playground now ignores log and clear-console messages from unauthorized sources, helping prevent unrelated windows from altering captured output.

Walkthrough

The playground iframe overrides console.clear and sends a clear message to the parent window. The captureLogs handler now processes messages only when event.source matches the playground iframe.

Priority: ⬇️ Low

Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to d468f

The playground now clears output in response to console.clear(), but untrusted window messages may still be able to clear a user's logs. Confirm the message sender is restricted to the playground iframe before merging.

Use interfaces for the message variants.

Define the 'log' and 'clear' variants as interfaces, then keep MessageEventData as the union alias.

Suggested refactor

-type MessageEventData =
-  | {
-      type: 'log';
-      log: [LogLevel, string];
-    }
-  | {
-      type: 'clear';
-    };
+interface LogMessageEventData {
+  type: 'log';
+  log: [LogLevel, string];
+}
+
+interface ClearMessageEventData {
+  type: 'clear';
+}
+
+type MessageEventData = LogMessageEventData | ClearMessageEventData;

As per coding guidelines, prefer interface over type for defining object shapes in TypeScript.

In `@website/src/routes/playground/index.tsx`:
- Line 184: Update the clear-message branch in the playground message handler to
call clearLogs() instead of assigning logs.value directly, ensuring
iframe-triggered clears emit clear_playground_logs consistently with button and
keyboard shortcut clears.
- Around line 183-184: Restrict the clear-message branch in the message handler
to events whose source equals iframeElement.value?.contentWindow before
assigning logs.value = []. Add a test confirming that a clear message from any
other source leaves the logs unchanged.
