Proposed fix: [E2B SDK] Resuming/connecting to a paused sandbox: 'Paused sandbox <id> not found' (404)
Recommended action: Treat as gone: create a new sandbox (persist state externally), check retention of paused sandboxes and the API key/team.

Steps:

2. Recreate if missing.
Expected: The error no longer appears.
