Migrate from contentlayer to content-collections

[paulgrammer]

Issue

On macOS, encountered a critical build issue with Contentlayer where the build process would hang indefinitely at:
Contentlayer config change detected. Updating type definitions and data...

Multiple attempted fixes were unsuccessful. This is a known issue tracked at haydenbleasel/next-forge#50 with no current resolution.

Solution

Migrated to Content Collections as a viable alternative. Content Collections provides similar functionality while avoiding the build issues present in Contentlayer.

Changes

• Removed Contentlayer configuration and dependencies
• Implemented Content Collections for content management
• Updated content processing logic
• Migrated existing content to new structure

Testing

• Verified build process completes successfully on macOS
• Confirmed content is properly rendered
• Tested content updates and rebuilds
