Update E2B launcher for SDK v2.0.2 API compatibility

- Fix template parameter to be positional argument instead of keyword
- Change env_vars to envs parameter (v2.0.2 API change)
- Update requirements.txt to use E2B SDK v2.0.2
- Based on official e2b-cookbook example for Anthropic Claude Code

Fixes WebSocket connection issues by using latest E2B SDK that no longer relies on WebSockets.
