Ramon Nogueira 5925a90a95 feat: migrate LangSmith sandbox creation to snapshot API (#1201) ... * feat: migrate LangSmith sandbox creation to snapshot API Replaces the template-based sandbox flow (DEFAULT_SANDBOX_TEMPLATE_NAME / DEFAULT_SANDBOX_TEMPLATE_IMAGE) with the new snapshot-based flow. - New required env var DEFAULT_SANDBOX_SNAPSHOT_ID (UUID of a pre-built LangSmith snapshot; build out-of-band via UI or SandboxClient.create_snapshot) - Optional DEFAULT_SANDBOX_SNAPSHOT_FS_CAPACITY_BYTES overrides the root FS size at boot (default 32 GiB) - Startup-time validation via a FastAPI lifespan hook: the server refuses to boot with a clear ValueError if SANDBOX_TYPE=langsmith and DEFAULT_SANDBOX_SNAPSHOT_ID is unset, so failures surface in boot logs rather than on the first thread - Reconnect-to-existing-sandbox path unchanged - Docs (INSTALLATION.md, CUSTOMIZATION.md) updated to describe the new snapshot workflow * fix: format create_sandbox_snapshot.py to pass ruff --------- Co-authored-by: aran-yogesh <yogesh.mahendran@langchain.dev>		2026-04-21 12:17:19 -07:00
