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.

+---
+
+# Version Detection Skill
+
+## Overview
+
+Find and parse version strings from all standard locations in a project. Supports multiple language ecosystems.
+
+## Detection Targets
+
+### Node.js / JavaScript
+| File | Pattern | Example |
+|------|---------|---------|
+| `package.json` | `"version": "X.Y.Z"` | `"version": "2.3.1"` |
+| `package-lock.json` | `"version": "X.Y.Z"` (root) | `"version": "2.3.1"` |
+
+### Python
+| File | Pattern | Example |
+|------|---------|---------|
+| `pyproject.toml` | `version = "X.Y.Z"` | `version = "2.3.1"` |
+| `setup.cfg` | `version = X.Y.Z` | `version = 2.3.1` |
+| `setup.py` | `version="X.Y.Z"` | `version="2.3.1"` |
+| `__version__.py` | `__version__ = "X.Y.Z"` | `__version__ = "2.3.1"` |
+
+### Rust
+| File | Pattern | Example |
+|------|---------|---------|
+| `Cargo.toml` | `version = "X.Y.Z"` | `version = "2.3.1"` |
+
+### Claude Marketplace
+| File | Pattern | Example |
+|------|---------|---------|
+| `marketplace.json` | `"version": "X.Y.Z"` | `"version": "2.3.1"` |
+| `plugin.json` | `"version": "X.Y.Z"` | `"version": "2.3.1"` |
+
+### Documentation
+| File | Pattern | Example |
+|------|---------|---------|
+| `README.md` | Title containing `vX.Y.Z` | `# Project - v2.3.1` |
+| `CHANGELOG.md` | `## [X.Y.Z]` | `## [2.3.1] - 2026-01-15` |
+
+## Git Tags
+
+Parse existing tags to determine latest released version:
+- `git tag --sort=-v:refname` — list tags by version
+- Support both `vX.Y.Z` and `X.Y.Z` formats
+- Detect the project's tag convention from existing tags
+
+## Version Parsing
+
+Extract and validate SemVer components:
+- Major, Minor, Patch (required)
+- Pre-release identifier (optional): `-alpha.1`, `-beta.2`, `-rc.1`
+- Build metadata (optional): `+build.123`
+
+Report any versions that do not conform to SemVer.
