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.

+# Docker Compose Patterns Skill
+
+Best practices and patterns for Docker Compose service definitions targeting self-hosted infrastructure.
+
+## Service Naming
+
+- Use lowercase with hyphens: `my-service`
+- Prefix with stack name for multi-project hosts: `myapp-db`, `myapp-redis`
+- Container name should match service name: `container_name: myapp-db`
+
+## Network Isolation
+
+Every stack should define its own bridge network:
+
+```yaml
+networks:
+  app-network:
+    driver: bridge
+```
+
+Services join the stack network. Only the reverse proxy entry point should be exposed to the host.
+
+## Volume Management
+
+- Use **named volumes** for data persistence (databases, uploads)
+- Use **bind mounts** for configuration files only
+- Set explicit permissions with `:ro` for read-only mounts
+- Label volumes with `labels` for identification
+
+```yaml
+volumes:
+  db-data:
+    labels:
+      com.project: myapp
+      com.service: database
+```
+
+## Healthchecks
+
+Every service MUST have a healthcheck:
+
+```yaml
+healthcheck:
+  test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+  start_period: 40s
+```
+
+Common healthcheck patterns:
+- HTTP: `curl -f http://localhost:<port>/health`
+- PostgreSQL: `pg_isready -U <user>`
+- Redis: `redis-cli ping`
+- MySQL: `mysqladmin ping -h localhost`
+
+## Restart Policies
+
+| Environment | Policy |
+|-------------|--------|
+| Development | `restart: "no"` |
+| Production | `restart: unless-stopped` |
+| Critical services | `restart: always` |
+
+## Resource Limits
+
+For Raspberry Pi (8GB RAM):
+
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 256M
+      cpus: '1.0'
+    reservations:
+      memory: 128M
+```
+
+## Dependency Ordering
+
+Use healthcheck-aware dependencies:
+
+```yaml
+depends_on:
+  db:
+    condition: service_healthy
+  redis:
+    condition: service_started
+```
+
+## Environment Variables
+
+Never inline secrets. Use `env_file`:
+
+```yaml
+env_file:
+  - .env
+  - .env.${DEPLOY_ENV:-development}
+```
+
+## Multi-Service Patterns
+
+### Web App + Database + Cache
+
+```yaml
+services:
+  app:
+    image: myapp:1.0.0
+    env_file: [.env]
+    depends_on:
+      db: { condition: service_healthy }
+      redis: { condition: service_healthy }
+    networks: [app-network]
+
+  db:
+    image: postgres:16-alpine
+    volumes: [db-data:/var/lib/postgresql/data]
+    healthcheck:
+      test: ["CMD", "pg_isready", "-U", "postgres"]
+    networks: [app-network]
+
+  redis:
+    image: redis:7-alpine
+    healthcheck:
+      test: ["CMD", "redis-cli", "ping"]
+    networks: [app-network]
+```
