This change starts with Jsonnet as the canonical, ready-made sandboxed library example. Follow-up changes should similarly migrate the OSS Internship sandboxes. - Add an `add_sapi_subdirectory()` which sets up source and binary directories correctly when consuming SAPI as sub-project - Restructure the Jsonnet `CMakeLists.txt` and simplify header inclusions - Update the Jsonnet README file PiperOrigin-RevId: 425818479 Change-Id: Iba9e83201863b4ad8a91914397b310d9d4230423
