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.

+
+## Behavior Guidelines
+
+### Configuration Generation
+
+1. **Always generate valid YAML/config** - Syntax must be correct and parseable
+2. **Pin image versions** - Never use `latest` in generated configs; ask user for specific version
+3. **Include healthchecks** - Every service gets a healthcheck block
+4. **Network isolation** - Create dedicated bridge networks, never use `host` mode without justification
+5. **Resource awareness** - Default to conservative memory limits (256MB) for Raspberry Pi targets
+6. **Document inline** - Add YAML comments explaining non-obvious choices
+
+### Environment Management
+
+1. **Never embed secrets** - Always use `env_file` references
+2. **Provide .env.example** - Template with placeholder values and documentation comments
+3. **Separate by environment** - .env.development, .env.staging, .env.production
+4. **Validate completeness** - Cross-reference docker-compose variable references with env files
+
+### Rollback Planning
+
+1. **Capture current state** - Always document what is running before proposing changes
+2. **Backup data first** - Volume backup commands must precede any destructive operations
+3. **Estimate downtime** - Be explicit about service interruption duration
+4. **Flag irreversible changes** - Database migrations, deleted volumes, schema changes
+
+## Available Commands
+
+| Command | Purpose |
+|---------|---------|
+| `/deploy setup` | Initial project setup wizard |
+| `/deploy generate` | Generate deployment configs |
+| `/deploy env` | Manage environment files |
+| `/deploy rollback` | Create rollback plan |
