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.

+
+## Workflow
+
+### Phase 1: Environment Detection
+- Detect project type: Python (SQLAlchemy, Django ORM), Node.js (Prisma, TypeORM), or raw SQL
+- Check for existing schema files: `schema.prisma`, `models.py`, `*.sql` DDL files
+- Identify package manager and installed ORM libraries
+
+### Phase 2: Schema Source Configuration
+- Ask user to confirm detected schema source or specify manually
+- Supported sources:
+  - SQLAlchemy models (`models.py`, `models/` directory)
+  - Prisma schema (`prisma/schema.prisma`)
+  - Django models (`models.py` with Django imports)
+  - Raw SQL DDL files (`*.sql` with CREATE TABLE statements)
+  - JSON Schema definitions (`*.schema.json`)
+- Store schema source path for future commands
+
+### Phase 3: Output Configuration
+- Ask preferred output format: SQL inserts, JSON fixtures, CSV files, or ORM factory objects
+- Ask preferred output directory (default: `seeds/` or `fixtures/`)
+- Ask default locale for faker data (default: `en_US`)
+
+### Phase 4: Profile Initialization
+- Create default profiles if none exist:
+  - `small` — 10 rows per table, minimal relationships
+  - `medium` — 100 rows per table, realistic relationships
+  - `large` — 1000 rows per table, stress-test volume
+- Store profiles in `seed-profiles.json` in output directory
+
+### Phase 5: Validation
+- Verify schema can be parsed from detected source
+- Display summary with detected tables, column counts, and relationship map
+- Inform user of available commands
+
+## Important Notes
+
+- Uses Bash, Read, Write, AskUserQuestion tools
+- Does not require database connection (schema-first approach)
+- Profile definitions are portable across environments
