Module Discovery and Auto-Import

This file handles module imports in two ways:

1. AUTO-DISCOVERY: Directory modules (new structure) are auto-imported

 - module-name/default.nix
 - Excludes directories starting with _ or .

2. EXPLICIT IMPORTS: Legacy single-file modules are imported explicitly

 - These are listed below and should be migrated to directory structure

The _template/ directory provides the template for new modules.

For fast metadata access without full evaluation, use:

config.stackpanel._moduleMetas.<module-id>
