Add inline code comments on commits
This feature enables users to add inline code comments on individual commits, similar to the existing PR code review functionality. Comments can be added, edited, and deleted on any line of a commit's diff. Changes: - Add service layer functions for commit comment CRUD operations - Add router handlers and API routes for commit comments - Add model queries to find commit comments - Update diff templates to show comment UI on commit pages - Load and display commit comments in the Diff() handler - Reuse existing PR comment templates and JavaScript Implements: #4898 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
