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.

+description: Pre-deployment health check — verify system readiness before deploying
+---
+
+# /deploy check
+
+Run pre-deployment health checks to verify the target system is ready.
+
+## Skills to Load
+
+- `skills/visual-header.md`
+- `skills/health-checks.md`
+
+## Agent
+
+Delegate to `agents/deploy-validator.md`.
+
+## Usage
+
+```
+/deploy check [--service=<name>] [--verbose]
+```
+
+**Options:**
+- `--service` - Check readiness for a specific service only
+- `--verbose` - Show detailed output for each check
+
+## Instructions
+
+Execute `skills/visual-header.md` with context "Pre-Deployment Check".
+
+### Phase 1: System Resources
+
+Run system checks using Bash tool:
+
+| Check | Command | Pass Condition |
+|-------|---------|----------------|
+| Disk space | `df -h /` | >10% free |
+| Memory | `free -m` | >256MB available |
+| CPU load | `uptime` | Load average < CPU count |
+| Temperature | `vcgencmd measure_temp` (RPi) or `/sys/class/thermal/` | <70C |
+
+### Phase 2: Docker Environment
+
+| Check | Command | Pass Condition |
+|-------|---------|----------------|
+| Docker daemon | `docker info` | Running |
+| Docker Compose | `docker compose version` | Installed |
+| Disk usage | `docker system df` | <80% usage |
+| Network | `docker network ls` | Expected networks exist |
+
+### Phase 3: Port Availability
+
+1. Read `docker-compose.yml` for all host port mappings
+2. Check each port with `ss -tlnp | grep :<port>`
+3. If port is in use, identify the process occupying it
+4. Flag conflicts as Critical
+
+### Phase 4: DNS and Network
+
+| Check | Command | Pass Condition |
+|-------|---------|----------------|
+| DNS resolution | `nslookup <subdomain>` | Resolves correctly |
+| Reverse proxy | `curl -s -o /dev/null -w "%{http_code}" http://localhost:80` | Caddy responding |
+| Tailscale | `tailscale status` | Connected (if applicable) |
+
+### Phase 5: Image Availability
+
+1. Parse `docker-compose.yml` for image references
+2. Run `docker pull --dry-run <image>` or `docker manifest inspect <image>`
+3. Verify images exist and support the target architecture (arm64 for RPi)
+4. Report image sizes and estimated pull time
+
+### Phase 6: Report
+
+```
+## Pre-Deployment Check Report
+
+### System Resources
+[OK]  Disk: 45% used (54GB free)
+[OK]  Memory: 1.2GB available
+[OK]  CPU: Load 0.8 (4 cores)
+[OK]  Temperature: 52C
+
+### Docker
+[OK]  Docker daemon: Running (v24.0.7)
+[OK]  Compose: v2.21.0
+[WARN] Docker disk: 72% used — consider pruning
+
+### Ports
+[OK]  8080 — Available
+[FAIL] 3000 — In use by grafana (PID 1234)
+
+### Network
+[OK]  DNS: myapp.hotport resolves
+[OK]  Caddy: Responding on :80
+
+### Images
+[OK]  postgres:16-alpine — arm64 available (89MB)
+[WARN] custom-app:latest — No arm64 manifest found
+
+### Summary
+- Passed: 10 | Warnings: 2 | Failed: 1
+- Status: NOT READY — fix port conflict on 3000
