Greptile Summary

This PR fixes YouTube transcript fetching by replacing the brittle web scraping approach with YouTube's ANDROID client API. The previous implementation scraped the video page HTML and parsed complex JSON structures, which broke when YouTube changed their internal structure. The new approach directly calls the YouTube API endpoint with proper client identification.

Key changes:

• Switched from HTML scraping to YouTube ANDROID client API (getVideoTranscript.ts:35-48)
• Simplified XML parsing using <p> tag extraction instead of complex JSON traversal (getVideoTranscript.ts:104-121)
• Added comprehensive test file for verifying transcript fetching (test/transcript.test.ts)
• Upgraded dependencies including @raycast/api, openai, and other packages
• Updated CHANGELOG following correct format with {PR_MERGE_DATE} placeholder

Minor issue:

• The youtube-transcript package was added to dependencies but is not used in the codebase

Confidence Score: 4/5

• Safe to merge with one minor optimization suggestion
• The core fix properly addresses the transcript fetching issue by switching from web scraping to the ANDROID client API. The implementation is clean with proper error handling. One unused dependency should be removed for cleanliness.
• No files require special attention
