* test: focus configuration diagnostics on their owners Preserve shape errors, selected paths, recovery guidance, and unchanged-file behavior across parser, setup, and uninstall boundaries. * test: focus artifact and evidence checks on behavior Retain format, identity, malformed-input, and cleanup coverage while removing fixed prose and closing the admitted test source. * refactor(debugger): use configured session admission limits * test: focus evidence and diagnostics on behavior * fix(test): restore verifier export and formatting * test(config): verify debugger limit ranges * test(rizin): keep fixture executable authoritative * test(rizin): isolate debugger fixture environment
