Add a new receiver application under cmd/receiver that accepts metrics
via HTTP POST and stores them in SQLite using GORM. The receiver expects
GitHub Actions style execution context (org, repo, workflow, job, run_id).

Add Go application that collects CPU and RAM metrics from /proc filesystem:
- Parse /proc/[pid]/stat for CPU usage (user/system time)
- Parse /proc/[pid]/status for memory usage (RSS, VmSize, etc.)
- Aggregate metrics across all processes
- Output via structured logging (JSON/text)
- Continuous collection with configurable interval
Designed for monitoring pipeline runner resource utilization to enable
dynamic runner sizing.
