Replace placeholder files with originals from system

Found and copied original files from ~/.claude installation:

- hooks/ - Original Qwen and Ralph hook scripts with full functionality
- commands/ - Original command definitions (brainstorm, write-plan, execute-plan)
- bin/ralphloop - Original 223-line Python wrapper (6,290 bytes)
- scripts/sync-agents.sh - Original sync script with GitHub/Gitea backup
- templates/ - Original config templates from working installation
- plugins/ - Original comprehensive plugin README

Files sourced from:
- ~/.claude/skills/skills/hooks/
- ~/.claude/skills/skills/commands/
- ~/.claude/skills/skills/templates/
- /home/uroma/obsidian-web-interface/bin/ralphloop
- ~/.claude/agents/sync-agents.sh

These are the production files from the working Claude Code
installation, replacing the placeholder files I created earlier.
