docs: restructure documentation into docs/ directory, slim README, add project .mcp.json
- README.md: reduced to overview + quick start + links to docs/
- docs/architecture.md: stack, design decisions, data models, key services
- docs/configuration.md: all env vars, docker-compose setup, production + security
- docs/development.md: dev workflow, CI/CD, migrations, release process
- docs/features.md: detailed feature breakdown + keyboard shortcuts
- docs/api-keys-and-mcp.md: API key management + Fable MCP install guide
- docs/sso-oauth.md: OAuth/OIDC setup (replaces docs/oauth-setup.md)
- docs/changelog.md: development history from summary.md
- Remove summary.md (content distributed across docs/)
- Remove docs/oauth-setup.md (superseded by docs/sso-oauth.md)
- .gitignore: add .mcp.json
