+/**
+ * Builds the E2B sandbox template that powers the Pi Coding Agent cloud mode.
+ *
+ * Layers the `pi` CLI plus git onto E2B's `code-interpreter` base (which already
+ * ships node + python). The cloud backend runs `pi` and `git clone/commit/push`
+ * inside this sandbox, so both must resolve on PATH — the global npm bin and
+ * `/usr/bin` both are.
+ *
+ * Usage:
+ *   E2B_API_KEY=... bun run apps/sim/scripts/build-pi-e2b-template.ts [--name <name>] [--no-cache]
+ *
+ * After it builds, set the printed value in the Sim app's .env:
+ *   E2B_PI_TEMPLATE_ID=<name>
+ * `Sandbox.create` resolves by template name, so use the name (not the ID).
