Release version 0.7.10

This commit adds the `pkgmgr_nix_store` volume mount (`/nix`) to all test
runners (unit, integration, container sanity checks, and E2E tests).

Previously only the Arch-based E2E container mounted a persistent `/nix`
store, causing all other distros (Debian, Ubuntu, Fedora, CentOS, etc.)
to download the entire Nix closure repeatedly during test runs.

Changes:
- Add `-v pkgmgr_nix_store:/nix` to:
  - scripts/test/test-container.sh
  - scripts/test/test-e2e.sh (remove Arch-only condition)
  - scripts/test/test-unit.sh
  - scripts/test/test-integration.sh
- Ensures all test containers reuse the same Nix store.

Benefits:
- Significantly faster test execution after the first run.
- Prevents redundant downloads from cache.nixos.org.
- Ensures consistent Nix environments across all test distros.

No functional changes to pkgmgr itself; only test infrastructure improved.
