feat: Universal Linux build + redesigned ostp-guard

- Build static musl binaries (work on any Linux distro)
- Redesign ostp-guard with weighted scoring system (threshold: 4 points)
  - HIGH (2pts): Analysis tools (gdb/ida/ghidra), sandbox artifacts
  - MEDIUM (1pt): Low resources (<1GB RAM), suspicious env vars
- Production VPS safe (1-2 points), sandbox blocked (4+ points)
- Anti-debug: Windows (IsDebuggerPresent), Linux (/proc/self/status)
- Deployment packages for Linux + Windows with SHA256 checksums
