Proposed fix: [E2B SDK] TemplateException 'You need to update the template to use the new SDK.' / '... to use recursive watching' / 'File metadata requires envd 0.6.2 or later.'
Recommended action: Rebuild the custom template with the current E2B CLI/build system so it gets a newer envd.
Option: Rebuild the custom template with the current E2B CLI/build system so it gets a newer envd. [evidence: official_recommended_action]

Steps:
1. Rebuild the template (e2b template build / Template SDK build)
2. Recreate sandboxes from the new template
3. Avoid the feature until rebuilt
Expected: The error no longer appears.
