feat(nix): Add Nix hooks to .pre-commit-hooks.yaml

[aRustyDev]

Description

Update the main .pre-commit-hooks.yaml configuration file to include all new Nix hooks.

Requirements

• Add configurations for all 6 new Nix hooks
• Ensure proper file patterns for each hook
• Set appropriate default arguments
• Mark hooks as tested after verification
• Update any relevant documentation

Hooks to add:

1. nix-flake-check
2. nix-build-check
3. nix-darwin-check
4. nix-home-manager-check
5. nix-fmt
6. nix-lint

Dependencies

This issue depends on the implementation of all individual hook issues:

• feat(nix): Implement nix-flake-check hook #15 nix-flake-check
• feat(nix): Implement nix-build-check hook #16 nix-build-check
• feat(nix): Implement nix-darwin-check hook #17 nix-darwin-check
• feat(nix): Implement nix-home-manager-check hook #18 nix-home-manager-check
• feat(nix): Implement nix-fmt hook #19 nix-fmt
• feat(nix): Implement nix-lint hook #20 nix-lint

Testing

• Verify each hook entry is valid YAML
• Test that pre-commit can parse the configuration
• Ensure file patterns match intended targets
• Verify hooks run correctly when installed
