Refine installer layering and Python/Nix integration

Browse Source 
- Introduce explicit CLI layer model (os-packages, nix, python, makefile)
  and central InstallationPipeline to orchestrate installers.
- Move installer orchestration out of install_repos() into
  pkgmgr.actions.repository.install.pipeline, using layer precedence and
  capability tracking.
- Add pkgmgr.actions.repository.install.layers to classify commands into
  layers and compare priorities.
- Rework PythonInstaller to always use isolated environments:
  PKGMGR_PIP override → active venv → per-repo venv under ~/.venvs/<identifier>,
  avoiding system Python and PEP 668 conflicts.
- Adjust NixFlakeInstaller to install flake outputs based on repository
  identity: pkgmgr/package-manager → pkgmgr (mandatory) + default (optional),
  all other repos → default (mandatory).
- Tighten MakefileInstaller behaviour, add global
  PKGMGR_DISABLE_MAKEFILE_INSTALLER switch, and simplify install target
  detection.
- Rewrite resolve_command_for_repo() with explicit Repository typing,
  better Python package detection, Nix/PATH resolution, and a
  library-only fallback instead of raising on missing CLI.
- Update flake.nix devShell to provide python3 with pip and add pip as a
  propagated build input.
- Remove deprecated/wip repository entries from config defaults and drop
  the unused config/wip.yml.
