[bot] Instrument E2B (1,253,397 weekly downloads)

js/src/auto-instrumentations/configs/all.tsから始め、既存のインストルメンテーションエントリを調べて統合パターンを確認します。Issueで挙げられているE2B SDKのサーフェスを確認し、その後、同等のカバレッジがあるかe2e/scenarios/を調べます。E2Bがレジストリに追加され、列挙されたSandbox.create、commands.run、runCodeのサーフェスがシナリオカバレッジ付きでインストルメントされていれば完了です。

Summary

E2B is an official cloud sandbox platform for running AI-agent-generated code and commands in isolated Firecracker microVMs. Its Node/TypeScript SDKs (e2b core, plus @e2b/code-interpreter for the code-execution surface) expose a meaningful agent-execution API — Sandbox.create(), sandbox.commands.run(), and sandbox.runCode() — that is not instrumented anywhere in this repository.

What's missing

• Sandbox.create() / sandbox.commands.run(...) (package e2b) — creates and drives a sandboxed execution environment for agent-run shell commands.
• sandbox.runCode(...) (package @e2b/code-interpreter) — executes LLM-generated code and returns structured results (stdout/stderr/results/error), the core "agent runs code" surface referenced in E2B's own AI-agent integration docs (including a documented OpenAI Agents SDK integration).

None of e2b, @e2b/code-interpreter, Sandbox.create, or runCode appear anywhere in js/src/, js/src/auto-instrumentations/configs/all.ts (the full registry of instrumented integrations), or any e2e/scenarios/* directory.
