Additive sandbox provider adapted to this fork's synchronous create_sandbox factory: agent/integrations/e2b.py registered as a lazy-import entry in SANDBOX_FACTORIES, so the e2b/langchain-e2b imports only load when SANDBOX_TYPE=e2b (dark-safe on unset env; unset E2B_API_KEY raises a clean ValueError only when the provider is selected). Supports reconnect-by-id and optional E2B_TEMPLATE. Non-langsmith providers skip the GitHub proxy step, so the GitHub-App token flow is untouched. Upstream: langchain-ai/open-swe 48217b68 (#1489), re-implemented against the fork's sync sandbox lifecycle rather than cherry-picked (upstream ships on the deferred async sandbox.py base). Docs: provider tables/lists in README, CUSTOMIZATION, INSTALLATION; the CUSTOMIZATION registration example now shows the lazy-tuple form the code actually uses. uv.lock refreshed (adds e2b, langchain-e2b, dockerfile-parse).
