// Exit code contract for every subcommand
// =========================================
//
// Default rule: every `Err(CliError)` arm below maps to exit code 1 (FAILURE).
// `Ok(code)` is returned verbatim, so each handler owns its own success codes.
//
//   add            0 on success (changeset written or dry-run preview)
//                  1 on any error (NotATty, invalid package spec, I/O, etc.)
//
//   status         0 when no errors and (no --check OR at least one pending changeset)
//                  1 when any diagnostic is Error-severity (or Warning under --strict)
//                  2 (ExitCode::from(2)) when --check is set and no changesets are pending
//
//   version        0 on success (versions bumped or dry-run preview)
//                  1 on any error (graph error, strict violation, etc.)
//
//   pre            0 on success
//                  1 on any error
//
//   validate       0 when the workspace passes all checks
//                  1 on any validation error or strict violation
//
//   snapshot       0 on success (snapshot versions applied or dry-run preview)
//                  1 on any error (graph error, strict crosscheck failure, etc.)
//
//   init           0 on success (configuration scaffolded or dry-run preview)
//                  1 on any error
//
//   plan-publish   0 on success
//                  1 on any error
//
//   publish        0 on success
//                  1 on any error
//
//   compose-pr-body  0 on success
//                    1 on any error
//
//   tag            0 on success (tags created or dry-run preview)
//                  1 on any error (graph error, strict crosscheck failure, etc.)
//
//   completions    0 on success
//                  1 on any error
