Greptile Summary

Adds linkHandler configuration to xterm.js Terminal options to properly handle OSC 8 hyperlinks (terminal escape sequence links), ensuring they open in the default browser instead of an Electron popup window.

• Extracts link-opening logic into a shared openLink function to reduce code duplication
• Respects custom options.onLinkClick handler when provided
• Simplifies WebLinksAddon handler to use the same centralized logic

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• Focused bug fix that correctly implements the xterm.js linkHandler API to handle OSC 8 hyperlinks. The implementation reduces code duplication, includes proper error handling, and has no breaking changes or security concerns.
• No files require special attention
