Summary:
This commit performs a major cleanup and modernization of the installation pipeline:

1. Introduced a new capability-detection subsystem:
   - Capabilities (python-runtime, make-install, nix-flake) are detected per installer/layer.
   - Installers run only when they add new capabilities.
   - Prevents duplicated work such as Python installers running when Nix already provides the runtime.

2. Removed deprecated pkgmgr.yml manifest installer:
   - Dependency resolution is now delegated entirely to real package managers (Nix, pip, make, distro build tools).
   - Simplifies layering and avoids unnecessary recursion.

3. Reworked OS-specific installers:
   - Arch PKGBUILD now uses 'makepkg --syncdeps --cleanbuild --install --noconfirm'.
   - Debian installer now builds proper .deb packages via dpkg-buildpackage + installs them.
   - RPM installer now builds packages using rpmbuild and installs them via rpm.

4. Switched from remote GitHub flakes to local-flake execution:
   - Wrapper now executes: nix run /usr/lib/package-manager#pkgmgr
   - Avoids lock-file write attempts and improves reliability in CI.

5. Added bash -i based integration test:
   - Correctly sources ~/.bashrc and evaluates alias + venv activation.
   - ‘pkgmgr --help’ is now printed for debugging without failing tests.

6. Updated unit tests across all installers:
   - Removed references to manifest installer.
   - Adjusted expectations for new behaviors (makepkg, dpkg-buildpackage, rpmbuild).
   - Added capability subsystem tests.

7. Improved flake.nix packaging logic:
   - The entire project source tree is copied into the runtime closure.
   - pkgmgr wrapper now executes runpy inside the packaged directory.

Together, these changes create a predictable, layered, capability-driven installer pipeline with consistent behavior across Arch, Debian, RPM, Nix, and Python layers.

Summary: Wrapper that runs Kevin's package-manager via Nix flake

BuildArch: noarch
Requires: nix
%description
This package provides the `pkgmgr` command, which runs Kevin's package
manager via a local Nix flake:
nix run /usr/lib/package-manager#pkgmgr -- ...
Nix is the only runtime dependency and must be initialized on the
system to work correctly.
