Subject: Add C4 architecture diagram skills for Claude Code

Two skills for generating C4 model diagrams as draw.io XML:
- /c4-analyze: generates diagrams from codebase analysis
- /c4-diagram: generates diagrams from conversational description

Includes Makefile for symlink-based install to ~/.claude/skills/.
