Add support for Lead Moderator badge

[Copilot]

Twitch's Lead Moderator role uses a distinct moderator_lead badge instead of the standard moderator badge, causing Lead Moderators to be incorrectly identified as non-moderators.

Changes

Updated badge checking in extractUserInfo() to recognize both badge types:

// Before
isMod: badges.some((badge) => badge.set_id === 'moderator'),

// After  
isMod: badges.some((badge) => badge.set_id === 'moderator' || badge.set_id === 'moderator_lead'),

This ensures all moderator privileges and permissions work correctly for Lead Moderators throughout the codebase.
