feat(install): add --update to re-run active-layer installers and improve Nix refresh logic
* Add `force_update` to `RepoContext` and propagate it through install/update flows
* Add `pkgmgr install --update` to force re-running installers even if the same CLI layer is already loaded
* Enhance `NixFlakeInstaller` to ensure correct outputs (pkgmgr + optional default for package-manager) and support refresh/upgrade with index-based fallback remove+reinstall
* Make Python/Makefile installers emit an “upgraded” marker when `force_update` is used
* Add E2E tests for “three times install” scenarios (makefile, nix, venv) with shared run helper
* Fix git safe.directory wildcard quoting in E2E shell runner and minor cleanup/reordering of imports/comments
