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.

+## Usage
+
+```
+/seed profile list
+/seed profile show <name>
+/seed profile create <name>
+/seed profile edit <name>
+/seed profile delete <name>
+```
+
+## Workflow
+
+### list — Show All Profiles
+- Read `seed-profiles.json` from configured output directory
+- Display table: name, row counts per table, edge case ratio, description
+- Highlight the default profile
+
+### show — Profile Details
+- Display full profile definition including:
+  - Per-table row counts
+  - Edge case configuration (null ratio, boundary values, unicode strings)
+  - Custom value overrides per column
+  - Locale settings
+  - Relationship density settings
+
+### create — New Profile
+- Ask user for profile name and description
+- Ask for base row count (applies to all tables unless overridden)
+- Ask for per-table overrides (optional)
+- Ask for edge case ratio (0.0 = no edge cases, 1.0 = all edge cases)
+- Ask for custom column overrides (e.g., `users.role` always "admin")
+- Save to `seed-profiles.json`
+
+### edit — Modify Profile
+- Load existing profile, display current values
+- Allow user to modify any field interactively
+- Save updated profile
+
+### delete — Remove Profile
+- Confirm deletion with user
+- Cannot delete the last remaining profile
+- Remove from `seed-profiles.json`
+
+## Profile Schema
+
+```json

+  "name": "medium",

+  "default_rows": 100,
+  "table_overrides": {
+    "users": 50,
+    "orders": 200,

+## Built-in Profiles
+
+| Profile | Rows | Edge Cases | Use Case |
+|---------|------|------------|----------|
+| `small` | 10 | 0% | Unit tests, quick validation |
+| `medium` | 100 | 10% | Development, manual testing |
+| `large` | 1000 | 5% | Performance testing, stress testing |
