#16536 a95d647 Thanks @WalshyDev! - Support remote Analytics Engine bindings in local development
Setting remote: true on an Analytics Engine dataset now sends writeDataPoint() calls from wrangler dev and the Vite plugin to the real dataset. Without it, writes are still dropped locally.
```
{
  "analytics_engine_datasets": [
    {
      "binding": "EVENTS",
      "dataset": "my-dataset",
      "remote": true
    }
  ]
}
```
#16489 fc57bc0 Thanks @akshitsinha! - Support standalone local Flagship access through the Local Explorer API
You can now list, create, update, delete, and evaluate flags for any local Flagship app by its ID, even when no Worker binds it and no dev server is running. This lets cf flagship commands manage local flags with --local.
Explorer Flagship routes now follow the public Flagship API: evaluate moves to /apps/{app_id}/evaluate, full updates use PUT, and PATCH changes only enabled, description, default_variation, and metadata. Flag metadata is stored, validated, and returned in evaluation results.
Explorer requests are no longer routed to the development process that owns each app. To share flags between local processes, use the same persistence directory.

#16492 a2dd5ff Thanks @Hrushikesh-ramilla! - Ensure Miniflare removes temporary files before disposal completes
#16521 ec6eddd Thanks @petebacondarwin! - Validate .assetsignore encoding before building asset manifests
Asset uploads and local development now stop with an actionable user error when .assetsignore is not valid UTF-8 or contains null characters, instead of silently losing its patterns. This also applies to standalone Miniflare and the Wrangler, Vite and Vitest development integrations. Save the file as UTF-8 to continue; UTF-8 files with a byte order mark and intentionally empty files remain supported.
