Implements horizontally-scalable worker pool architecture:
- claudebox-sidecar: HTTP server for Claude Code, git, and SDLC ops
- rdev-worker: standalone worker binary polling rdev-api for tasks
- HTTP client adapter for sidecar communication
- HPA with custom Prometheus metrics for autoscaling
- ServiceMonitor for metrics scraping
Code review fixes applied:
- URL-encode query parameters in GitStatus (Critical #1)
- Remove unused shellQuote function (Critical #2)
- Use stdlib strings.Split/TrimSpace (Critical #3)
- Add version injection via ldflags (Warning #4)
- Add debug logging for swallowed git/sdlc errors (Warning #5, #6)

- Add POST /workers/register and POST /workers/{workerId}/heartbeat endpoints
- Start worker health checker goroutine in main.go
- Fix network policy to allow K8s API server access (includes real endpoint IPs)
- Add rdev.orchard9.ai/role: worker label to claudebox StatefulSet
This enables the embedded WorkExecutor to reach claudebox-0 for executing
builds on composable projects that don't have dedicated pods.
