Add a reusable retry helper that detects GitHub API 403 rate-limit errors
during Nix flake evaluation and retries with exponential backoff.
Apply the retry logic to flake-only CI tests so transient GitHub rate
limits no longer cause random CI failures while preserving fast failure
for real errors.

Refactor Dockerfile into multi-stage virgin/full targets and introduce a single
flag-based image build script. Standardize image naming, remove redundant build
scripts, and update Makefile targets accordingly. CI workflows now build missing
virgin images and run root and user tests consistently across all supported
distributions.

* Switch virgin root/user workflows to use *make install* + *make setup/setup-venv*
* Add Git *safe.directory /src* to avoid flake evaluation failures on mounted repos
* Enable Nix flake run in workflows and prepare */nix* for non-root execution
* Refactor Arch packaging to build in an isolated */tmp* directory via *aur_builder*
* Rename installer scripts (*run-** → *dependencies.sh* / *package.sh*) and adjust Docker entry + env var to *REINSTALL_PKGMGR*

Refactor CI to clearly separate virtualenv-based container tests from pure Nix flake tests across all distros (arch, debian, ubuntu, fedora, centos).
Introduce dedicated test-env-nix workflow and Makefile targets, rename former container tests to test-env-virtual, and update stable pipeline dependencies.
Improve Nix reliability in containers by fixing installer permissions and explicitly validating nix availability and version during image build and tests.
