Nixorium v2.0.0-beta.2

Added

• A reusable lib.mkLab Flake API with typed lab configuration validation.
• A site Flake template for private per-lab deployment repositories.
• Extension points for shared, controller, client, host-specific and netboot modules.
• Configurable logo, backgrounds, MIME defaults, VS Code settings and public key paths.
• A standalone netboot installer bundle containing the effective downstream configuration.
• A portable repository-maintainer Agent Skill, preinstalled by the site template for Codex, OpenCode, Claude Code and Pi.

Changed

• Operational Harmonia and PXE helpers are exposed as Flake apps for downstream repositories.
• Lab-specific configuration can now update the upstream through a pinned Flake input instead of Git merges.
• The upstream screensaver logo is generic and site-specific printer drivers are delegated to deployment modules.
