Begin the Python 3.15 essential-library bootstrap

Target Python 3.15.0alpha and import site, pkgutil, importlib and supporting test libraries from CPython v3.15.0rc2 (435c9e5a798c99653e3ab64ce29baed0e4f3dfee). Keep native atomic module-cache movement at the surviving importlib reorder sites and use the canonical builtin import callback. Preserve explicit temporary eager-import and readonly-table adaptations while their full PEP implementations remain separate. This starts the migration and does not claim complete 3.15 bytecode or runtime compatibility. Assisted-by: Codex:model-version-unavailable
