Collect feedback on current issue systems for GitHub Revamp

## Description

Gather and document feedback on the current GitHub issue label and triage systems across Azure SDK repos. This feeds into the GitHub Systems Revamp project to identify what's working, what's redundant, and what should change.

## Goal

Compile stakeholder feedback into a structured analysis that can inform label consolidation, triage improvements, and platform feature adoption (e.g., sub-labels, issue types, discussions).

Start by reviewing the current GitHub issue label and triage systems across Azure SDK repositories. Gather stakeholder feedback on what works, what is redundant, and what should change, then organize it into a structured analysis covering label consolidation, triage improvements, and platform features such as sub-labels, issue types, and discussions. Done means the analysis can inform the GitHub Systems Revamp project.
