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.

"""
Repository installation pipeline for pkgmgr.
High-level entry point for repository installation.
This module orchestrates the installation of repositories by:
Responsibilities:
1. Ensuring the repository directory exists (cloning if necessary).
2. Verifying the repository according to the configured policies.
3. Creating executable links using create_ink(), after resolving the
appropriate command via resolve_command_for_repo().
4. Running a sequence of modular installer components that handle
specific technologies or manifests (PKGBUILD, Nix flakes, Python
via pyproject.toml, Makefile, OS-specific package metadata).
The goal is to keep this file thin and delegate most logic to small,
focused installer classes.
- Ensure the repository directory exists (clone if necessary).
- Verify the repository (GPG / commit checks).
- Build a RepoContext object.
- Delegate the actual installation decision logic to InstallationPipeline.

- Skip installers whose layer is weaker than an already-loaded one.

Resolve the executable command for a repository.
Variant B implemented:
-----------------------
If the repository explicitly defines the key "command" in its config,
the function immediately returns that value — even if it is None.
Semantics:
----------
- If the repository explicitly defines the key "command" (even if None),
that is treated as authoritative and returned immediately.
This allows e.g.:
This allows a repository to intentionally declare:
command: null
meaning it does NOT provide a CLI command and should not be resolved.
command: null
This bypasses:
- Python package detection
- PATH / Nix / venv binary lookup
- main.py / main.sh fallback logic
- SystemExit errors for Python packages without installed commands
for pure library repositories with no CLI.
If "command" is NOT defined, the normal resolution logic applies.
- If "command" is not defined, we try to discover a suitable CLI command:
1. Prefer already installed binaries (PATH, Nix profile).
2. For Python src-layout packages (src/*/__main__.py), try to infer
a sensible command name (alias, repo identifier, repository name,
package directory name) and resolve those via PATH / Nix.
3. For script-style repos, fall back to main.sh / main.py.
4. If nothing matches, return None (no CLI) instead of raising.
The caller can interpret:
- str → path to the command (symlink target)
- None → no CLI command for this repository
