fix(cli): migration failures reach the CLI exit code

+- CLI: migration failures now reach the exit code. A failed `up()`/`down()` step that `migrateTo()` folds into its output (e.g. `Error migrating to <version>.`) made `wheels migrate latest|up|down` print the error inside the green success block and still exit 0; `wheels db reset --force` exited 0 when it refused on a `ServerNotRunning` check; and `wheels migrate forget|pretend` refusals (not in tracking table, matching local file exists, already applied, no matching file) printed red but exited 0. All three now exit non-zero, so a `wheels migrate latest && …` CI gate no longer proceeds as if the schema moved. Informational dry-run output (missing `<version>` / missing `--yes`) still exits 0. The migrate-side sibling of the #2973/#2987 seeder honesty fix (#3081)
