Compile the System Application and/or System Application Tests AL-Go projects locally without spinning up a Business Central container. Use after editing AL code under `src/System Application/` or `src/Business Foundation/` to confirm the change still builds, or when the user asks to "compile system app", "build the test app", or similar.
Run specific AL test codeunits against an existing Business Central container. Requires a running container and at least one filter (codeunit ID, range, function, or extension ID) — will not run all tests.
