hermes_cli.runtime_paths (venv generations, selection, activation) moves to pm.environments, and gains venv_bin_dir / venv_python / project_python. Every in-tree caller asks pm for an interpreter now; pm no longer reaches back into hermes_cli for its own environment layout (pm.packages, pm.extras, pm.ensure, pm.paths imported hermes_cli.runtime_paths). The three open-coded "Scripts/python.exe or bin/python" ladders in pm collapse onto venv_python. hermes_constants.venv_python_path / venv_bin_dir and hermes_cli.runtime_paths stay as frozen-updater-surface shims only (tests/compat/old_updater_surface.json). To keep the boot path light, pm/__init__ resolves its facade lazily (PEP 562) and pm.registry loads the built-in package definitions on first read instead of at import: `import hermes_bootstrap` now loads pm + pm.environments only (25ms, was 37ms with the eager facade dragging in the downloader). The stripped-payload fixtures that ship only pre-import files keep working for the same reason. Also restores two frozen-surface re-exports the F401 sweep dropped (banner._github_compare_behind, cua_backend.resolve_cua_driver_cmd).
