Proposed fix: [Wrangler] 'Cannot use assets and Workers Sites in the same Worker' when migrating a [site] Worker to static assets
Recommended action: Remove the `site` block (and __STATIC_CONTENT/kv-asset-handler code) when moving to `assets`, or keep only `site`.
Option: Keep only assets [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Delete [site] from wrangler config
2. Configure assets.directory (and binding if needed)
3. wrangler deploy
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
