refactor: extract option definitions into separate files

[vic]

• Create modules/_options/ directory with individual option files
• Split large options.nix into modular components:
  • do-not-edit.nix: header comment option
  • formatter.nix: flake formatter configuration
  • inputs.nix: flake inputs with follows support
  • outputs.nix: outputs function configuration
  • prune-lock.nix: lock pruning options
• Simplify main options.nix using dynamic imports
• Improve code organization and maintainability

Pull Request Overview

This refactoring extracts option definitions from a monolithic options.nix file into separate modular files organized in a modules/_options/ directory. The change improves code organization and maintainability by splitting large configuration definitions into focused, single-responsibility modules.

Key changes:

• Split large options.nix into 5 separate option modules (do-not-edit, formatter, inputs, outputs, prune-lock)
• Implement dynamic imports using lib.pipe to reconstruct the options structure
• Maintain existing functionality while improving code organization
