feat(enhanced): support shared module layers

[ScriptedAlchemy]

Description

This pull request enhances the module sharing functionality in the enhanced package by implementing comprehensive layer support and improving schema validation. The changes focus on the compiler mechanics for module layers, with runtime updates planned for a future PR.

https://github.com/module-federation/core/issues/3153

Key Changes

1. Schema Validation Enhancements

   • Added TypeScript-based validation for ConsumeSharedPlugin schema
   • Enhanced ProvideSharedPlugin schema with layer support
   • Added new properties for layer configuration:

     layer: {
       description: 'Layer for the shared module.',
       type: 'string',
       minLength: 1
     },
     issuerLayer: {
       description: 'Layer in which the issuer should be.',
       type: 'string',
       minLength: 1
     }
     

2. Module Resolution Improvements

   • Enhanced request key creation with layer support
   • Updated module resolution logic to handle layer-specific requests
   • Improved handling of relative, absolute, and module requests
   • Added support for composite keys in module resolution

3. Share Configuration Updates

   • Added layer support to normalizeConsumeShareOptions
   • Enhanced share scope management with layer awareness
   • Updated module matching logic to consider layer context
   • Improved type definitions for shared module configurations

Example Configuration

new SharePlugin({
  shareScope: ['rsc','default'],
  shared: {
    react: {
      singleton: true,
    },
    'explicit-layer-react': {
      request: 'react/index2',
      import: 'react/index2',
      shareKey: 'react',
      singleton: true,
      issuerLayer: 'differing-layer',
      layer: 'explicit-layer',
    }
  }
})

Technical Implementation Details

• [utils.ts]: Enhanced module resolution with layer support
• [ConsumeSharedPlugin.check.ts]: Added comprehensive schema validation
• [ProviderSharedPlugin.ts]: Updated schema with layer properties
• Added support for composite keys in module resolution
• Improved error handling for module resolution failures

Note

This PR focuses on the compiler mechanics for module layers. Runtime module aspects will be updated in a subsequent PR.
