• Changed the database helper to return full rows instead of a boolean and removed the duplicate Twitch helper.
• Updated both YouTube and Twitch handlers to retrieve tracked channels and list them in the error message.

[nitpick] For a two-item list this will render <#A>, and <#B> (with an extra comma). You might want to handle the two-item case specially or use a small utility to format lists in natural language.
