feat(marketplace): command consolidation + 8 new plugins (v8.1.0 → v9.0.0) [BREAKING]

Phase 1b: Rename all ~94 commands across 12 plugins to /<noun> <action>
sub-command pattern. Git-flow consolidated from 8→5 commands (commit
variants absorbed into --push/--merge/--sync flags). Dispatch files,
name: frontmatter, and cross-reference updates for all plugins.

Phase 2: Design documents for 8 new plugins in docs/designs/.

Phase 3: Scaffold 8 new plugins — saas-api-platform, saas-db-migrate,
saas-react-platform, saas-test-pilot, data-seed, ops-release-manager,
ops-deploy-pipeline, debug-mcp. Each with plugin.json, commands, agents,
skills, README, and claude-md-integration. Marketplace grows from 12→20.

+## API Platform Integration
+
+This project uses the saas-api-platform plugin for API development workflows.
+
+### Configuration
+
+Run `/api setup` to auto-detect framework and configure project paths.
+Settings stored in `.api-platform.json` in project root.
+
+### Available Commands
+
+| Command | Purpose |
+|---------|---------|
+| `/api setup` | Detect framework and configure project |
+| `/api scaffold <resource>` | Generate CRUD routes, models, schemas |
+| `/api validate` | Check routes against OpenAPI spec |
+| `/api docs` | Generate/update OpenAPI specification |
+| `/api test-routes` | Generate endpoint test cases |
+| `/api middleware <type>` | Add auth, CORS, rate-limit, logging |
+
+### When to Use
+
+- **Starting a new resource**: `/api scaffold orders` generates routes, models, and registers the router
+- **Before PR/deploy**: `/api validate` ensures spec and code are in sync
+- **After route changes**: `/api docs --update` refreshes the OpenAPI spec
+- **Adding infrastructure**: `/api middleware auth` adds JWT authentication
+- **Before release**: `/api test-routes --coverage=full` generates comprehensive tests
+
+### Conventions
+
+- All routes follow RESTful naming (plural nouns, no verbs in paths)
+- Versioning via URL prefix (`/v1/`) when configured
+- Pagination on all list endpoints (page, page_size parameters)
+- Consistent error response format with error codes and request IDs
+```
+
+## Typical Workflows
+
+### New Resource
+```
+/api scaffold products
+/api docs --update
+/api test-routes products
+/api validate
+```
+
+### Add Authentication
+```
+/api middleware add auth
+/api validate --strict
+```
+
+### Pre-Release Check
+```
+/api validate --strict
+/api test-routes --coverage=full
+```
