chore: move Claude Code config to version control

[vredchenko]

Summary

Move unversioned Claude Code configuration from workspace root to smartem-devtools/claude-code/ and symlink back. Additionally, add CLI commands to verify and repair workspace setup.

Current State

~/dev/ERIC/                    # workspace root (not a git repo)
├── CLAUDE.md                  # unversioned (copy)
├── claude-config/             # symlink ✓
├── .claude/
│   ├── settings.local.json    # created by CLI
│   └── skills/                # EMPTY (bug: wrong paths in config)

Target State

smartem-devtools/claude-code/
├── CLAUDE.md                  # versioned
├── ARCHITECTURE.md            # versioned
├── shared/skills/             # versioned skills
└── ...

~/dev/ERIC/
├── CLAUDE.md → repos/.../smartem-devtools/claude-code/CLAUDE.md
├── claude-config → repos/.../smartem-devtools/claude-code/
├── .claude/

Benefits

• Claude Code config becomes version controlled
• Changes are trackable and reviewable
• Shared across team via smartem-workspace CLI setup
• check command can verify and repair setup

Implementation

1. ✅ Move files to smartem-devtools/claude-code/ (done previously)
2. ✅ Create claude-config symlink (done in CLI)
3. ⬜ Fix skill paths in repos.json (missing claude-code/ prefix)
4. ⬜ Change CLAUDE.md from copy to symlink
5. ⬜ Implement smartem-workspace check [--fix] command
6. ⬜ Implement smartem-workspace sync command

CLI Commands (New)

# Verify workspace setup
smartem-workspace check
smartem-workspace check --scope claude
smartem-workspace check --scope repos

# Repair issues
smartem-workspace check --fix

# Pull latest from remotes
smartem-workspace sync
smartem-workspace sync --dry-run
