Add friend library comparison and game comments features

- CompareController: side-by-side library diff with stats (common games, rating diff) - GameCommentController + GameCommentPolicy: threaded comments with replies, auth-gated - GameComment model with top-level scope and self-referential replies relation - Migration: game_comments table with parent_id for threading - games/show: Discussion section with Alpine.js (post, reply, delete) - compare/show: tabbed view (in common, they have, you have) with game cards - users/show: "Compare Libraries" button visible to other authenticated users Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
