PR Summary

Medium Risk
Changes Pi cloud sandbox images and shared build scripts; risk is operational (must rebuild templates) rather than auth/data, but failover parity between E2B and Daytona depends on both images being rebuilt.

Overview
Pi Create PR / Update PR / Review Code sandboxes now ship Bun alongside the existing Pi CLI, Git, and Node.js stack. The repo-pinned version (1.3.13, from the root packageManager) is installed globally via bun@… in the shared PI_GLOBAL_NPM_PACKAGES list (renamed from PI_NPM), and both E2B and Daytona image builders run PI_BUN_VERSION_ASSERT so a wrong Bun version fails the image build instead of at runtime.

Docs for Create PR setup now state that repository dependencies are not preinstalled and that Pi can run bun install when a cloned repo needs them.

Rebuild E2B and Daytona Pi images after merge so production sandboxes pick up Bun.

Greptile Summary

Installs the repository-pinned Bun release in both cloud sandbox images and documents that repository dependencies remain runtime-installed.

• Adds Bun 1.3.13 to the shared global package list and verifies its version during image builds.
• Applies the shared installation and assertion to the E2B template and Daytona snapshot.
• Updates Pi documentation to list Bun among the preinstalled tools and clarify that dependencies are not preinstalled.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness or security failures identified.

The Bun pin matches the repository package-manager version, both image providers consume the same package list, and each build now fails immediately if the installed runtime does not match the expected version.

Important Files Changed

Filename	Overview
apps/sim/scripts/pi-sandbox-packages.ts	Pins Bun 1.3.13, includes it in the shared global package list, and defines an exact build-time version assertion.
apps/sim/scripts/build-pi-e2b-template.ts	Installs the shared global packages into the E2B image and validates the installed Bun version.
apps/sim/scripts/build-pi-daytona-snapshot.ts	Installs the same shared global packages into the Daytona image and validates Bun before completing the snapshot.
apps/docs/content/docs/en/workflows/blocks/pi.mdx	Documents Bun as preinstalled while clarifying that repository dependencies still require installation.
