Sync global CLAUDE.md rules via claude-code-sync

[J-MaFf]

Problem

The global CLAUDE.md in ~/Documents/Scripts/ is not version-controlled or synced across machines, so rules are lost on a new machine setup.

Solution

• Store CLAUDE.md in rules/CLAUDE.md inside the sync repo
• claude-sync-push: collect CLAUDE.md from $CLAUDE_SCRIPTS_DIR into rules/ before committing
• claude-sync-pull: deploy rules/CLAUDE.md to $CLAUDE_SCRIPTS_DIR after syncing
• Add CLAUDE_SCRIPTS_DIR config variable (defaults to ~/Documents/Scripts)
• Document in .claude-sync-config.example
