feat: project refactoring - folder cleanup, governance, and automation

Project Structure Cleanup:
- Remove deprecated cmdb-assistant plugin
- Remove development output files (test scripts, status reports)
- Remove IDE-specific workspace files
- Create scripts/ directory for automation
- Create docs/architecture/ for Draw.io diagrams
- Create docs/workflows/ for workflow documentation
- Create .scratch/ directory for transient work

Governance & Documentation:
- Add File Creation Governance section to CLAUDE.md
- Add architecture diagram specifications (component-map, agent-workflow)
- Add docs/UPDATING.md with update workflow
- Update CHANGELOG.md with all changes

Installation Automation:
- Add scripts/setup.sh for initial installation
- Add scripts/post-update.sh for updates after git pull
- Add /initial-setup slash command

Maintenance:
- Update .gitignore with scratch directory
- Fix all project name references (use support-claude-mktplace)

+# Initial Setup
+
+Run the installation script to set up the toolkit.
+
+## What This Does
+
+1. Creates Python virtual environments for MCP servers
+2. Installs all dependencies
+3. Creates configuration file templates
+4. Validates existing configuration
+5. Reports remaining manual steps
+
+## Execution
+
+```bash
+cd ${PROJECT_ROOT}
+./scripts/setup.sh
+```
+
+## After Running
+
+Review the output for any manual steps required:
+- Configure API credentials in `~/.config/claude/`
+- Run `/labels-sync` to sync Gitea labels
+- Verify Wiki.js directory structure
+
+## Re-Running
+
+This command is safe to run multiple times. It will skip already-completed steps.
