Minor Changes

• #12462 f239077 Thanks @petebacondarwin! - Add Miniflare#purgeCache() method to clear cache entries programmatically

  This allows developers to clear cached data during local development without
  restarting the Miniflare instance. Useful when working with Workers Sites
  or any application that uses the Cache API.

  const mf = new Miniflare({
  	/* options */
  });
  
  // Purge the default cache
  await mf.purgeCache();
  
  // Purge a specific named cache
  await mf.purgeCache("my-named-cache");

• #12574 527e4f5 Thanks @emily-shen! - Local explorer: add /query endpoint to introspect sqlite in DOs

  This required adding a wrapper that extends user DO classes and adds in an extra method to access ctx.storage.sql. This shouldn't have any impact on user code, but is gated by the env var X_LOCAL_EXPLORER.

  This is for an experimental WIP feature.
