Reorganize repository structure and clean up documentation

Clean up and organize the flask-shopdb repository for better
maintainability and discoverability:

## Changes

- Update .gitignore for build artifacts (publish/, data/, 122M total)
- Reorganize .claude/ into 6 subdirectories with README navigation
- Consolidate overlapping MCP setup guides into MCP-QUICK-START.md
- Move deployment docs from root to docs/deployment/
- Archive dated status reports to .claude/archived/
- Delete temporary files (logs, backups, empty reports, ~50K)

## New Structure

.claude/ organized into:
- setup/ - MCP, VM, Hyper-V, GitHub setup guides + scripts (17 files)
- plans/ - Feature plans and protocols (5 files)
- maintenance/ - Deployment checklists and reports (4 files)
- archived/ - Historical documentation (9 files)
- skills/ - Claude Code automation (5 files)
- workflows/ - Security audit workflow (1 file)

docs/deployment/ created with 6 deployment guides:
- LOCAL-DEV-SETUP.md, DOCKER-SETUP.md, DOCKER-PREBUILT-APPROACH.md
- PRODUCTION-READINESS.md, DEPLOY-TO-VM.md, README.md

Root directory cleaned to essential docs only:
- CLAUDE.md, README.md, CONTRIBUTING.md, CHANGELOG.md

Benefits:
- Clear navigation via README.md in each subdirectory
- No duplicate/overlapping documentation
- Large artifacts properly gitignored (won't bloat repository)
- Historical context preserved in archived/

See .claude/CLEANUP-SUMMARY.md for complete details.
