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.

+## Skills to Load
+- skills/visual-output.md
+- skills/plugin-discovery.md
+- skills/interface-parsing.md
+- skills/dependency-analysis.md
+- skills/mcp-tools-reference.md
+
+## Usage
+
+```
+/cv dependency-graph [marketplace_path] [--format <mermaid|text>] [--show-tools]
+```
+
+## Parameters
+
+- `marketplace_path` (optional): Path to marketplace root. Defaults to current project root.
+- `--format` (optional): Output format - `mermaid` (default) or `text`
+- `--show-tools` (optional): Include individual tool nodes in the graph
+
+## Workflow
+
+1. **Display header** per `skills/visual-output.md`
+
+2. **Discover plugins** per `skills/plugin-discovery.md`
+
+3. **Parse interfaces** per `skills/interface-parsing.md`
+   - Use `parse_plugin_interface` for each plugin
+   - Use `parse_claude_md_agents` for CLAUDE.md
+
+4. **Analyze dependencies** per `skills/dependency-analysis.md`
+   - Identify shared MCP servers
+   - Detect data producers/consumers
+   - Categorize as required or optional
+
+5. **Generate output**:
+   - Mermaid: Create flowchart TD diagram with styled edges
+   - Text: Create text summary with counts and lists
+
+## Examples
+
+```
+/cv dependency-graph
+/cv dependency-graph --show-tools
+/cv dependency-graph --format text
+/cv dependency-graph ~/claude-plugins-work
+```
+
+## Integration
+
+Use with `/cv validate`:
+1. Run `/cv dependency-graph` to visualize
+2. Run `/cv validate` to find issues
+3. Fix and regenerate
