Add GitHub-style activity grid showing development contributions: - Activity grid with color-coded commit intensity - Total stats: commits, files changed, lines added/removed - Contributors section with commit counts - Recent activity list Extended devlog schema with: - stats: filesChanged, linesAdded, linesRemoved - contributors: name, handle, commits per contributor - workingHours: start/end timestamps Updated all 9 devlogs with accurate git stats. Added link to activity page from devlog index.
