- Removed SubscriptionsList and channel subscription UI - Simplified Navigation component (removed compose link and channel list) - Updated Drawer component to remove channel and post references - Removed unused discussion HOCs (withChannelHeader, withChannelTracker, withPostList, withPostModeration) - Frontend now builds successfully with webpack Build Status: ✅ SUCCESS (only SASS deprecation warnings) Modules compiled: 640+ modules No compilation errors

Code Review
This is an impressive pull request that methodically removes the discussions/channels feature from the frontend. The code changes are clean, consisting mainly of deletions and simplifications that are consistent with the PR's goal. The most commendable part of this work is the extensive and well-structured documentation you've added. The detailed plans for removal, testing, rollback, and even AI agent guidance are exemplary and will be invaluable for anyone involved in this process. I have one minor formatting suggestion for the new documentation files.

Minor formatting suggestion: there are two spaces after 'team'. This trailing whitespace appears in several of the new documentation files. For consistency and cleaner markdown, it would be good to do a quick search for double spaces at the end of lines and remove them.
