v0.2.3 - Git Commit & Lines Changed Tracking

What's New

Git & Shipping Stats

• Lines Added overview card replaces "Files Touched" on the dashboard homepage, showing total lines added with commit count and lines removed in the subtitle
• Git & Shipping section in the Stats tab with Total Commits, Lines Added, Lines Removed, Net Lines, and Files Touched
• Parses git commit tool output already stored in the database — no schema changes needed
• Tracks commits made through AI coding tools (Claude Code, Gemini CLI, etc.) during sessions

Under the Hood

• New parseGitDiffStats helper for extracting insertions/deletions from git's --stat summary
• totalLinesAdded and totalLinesRemoved wired into the badge system for future achievements
• 8 new tests covering commit counting, line parsing, and edge cases
