Correct quote escaping, replacement count keyword binding, signed-minimum hex grouping, and clear storage/export handling. Migrate canonical bytes coverage through fail-closed preservation of the existing RustPython customizations, and retire only two freshly verified formatting guards.

* Align OS argument conversion and syscall handling with Python 3.15
Import canonical os tests through update_lib, retaining existing guards. Preserve raw descriptor validation, errno, audit ordering, signal retries and unlocked sendfile buffers.
Validation: independent source review passed; matching release build and nine bounded canonical cases pending.

* Import canonical root-user test support for OS package
Add hash-pinned selective assignment migration within test.support and import the three Python 3.15.0 privilege helpers plus their public exports. Preserve unrelated support helpers and existing test markers.
Validation: 177 host updater tests pass; byte-identical canonical helper provenance verified. Independent source review passed. Native import validation pending integration onto current main.

* Preserve explicit customizations during canonical library migration
Add bounded runtime, call, and doctest preservation plus explicit remaining-marker metadata. Support mapped legacy test-package migrations without losing ordered guards, and exclude cache directories from both migration paths while retaining canonical assets.
Validation: 53 bounded host-Python tooling tests passed. Tests inspect source and temporary files without executing migrated fixtures. Existing copy-library cache protection is unchanged. No Lib or interpreter changes.

* Integrate migration preservation into existing updater modules
Keep migration orchestration and guarded package moves in cmd_migrate, and marker/doctest metadata in patch_spec. Reuse AST anchor validation and existing test modules, removing all eleven newly introduced helper, test, and data files.
Require caller-selected doctest metadata instead of embedding syntax-case policy. Reject guarded legacy doctests before package writes. Preserve the prior 53 test scenarios and add seven focused metadata regressions; all 60 bounded host tooling tests passed. No Lib, workflow, or native changes.
