Reviewer's Guide

This PR enhances the role assignment logic by catching and handling discord.NotFound errors—specifically to detect if a member has left or been kicked before a delayed role assignment—and logs accordingly to avoid silent failures.

File-Level Changes

Change	Details	Files
Add explicit handling for NotFound errors during delayed role assignment	Wrap member.add_roles in except discord.NotFound Verify member still exists in guild before retry Log info if member left/kicked; log error otherwise	tux/cogs/services/tty_roles.py

suggestion: Consider lowering log level for expected NotFound errors

If a missing member is truly unexpected, keep the error level; otherwise (e.g. role deletion or race condition), switch to warning or debug to reduce log noise.
