Summary of Changes

Hello @kaloudis, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new feature to support nested URI schemes, specifically those prefixed with LIGHTNING: and containing LNURL types like lnurlp://. This enhancement allows the application to correctly interpret and process these complex URIs, improving compatibility and user experience when dealing with various Lightning Network payment requests and operations.

Highlights

• Nested URI Scheme Support: Implemented support for nested URI schemes, specifically those prefixed with LIGHTNING: and containing LNURL types such as lnurlp://, lnurlw://, lnurlc://, and lnurlauth://.
• URI Conversion Logic: The system now correctly parses these nested URIs, converting lnurlp:// and similar schemes to standard https:// for regular domains or http:// for .onion addresses before further processing.
• Comprehensive Unit Testing: Added extensive unit tests to validate the correct parsing and processing of various nested LNURL URI schemes, covering different cases, types (pay, withdraw, channel), and address formats (including .onion).
