v1.0.0 Release - All Phases Complete

Phase 2: Core API Development
- 15 REST API endpoints (packages, patches, system, jobs, websocket)
- mTLS authentication layer (src/auth/mtls.rs)
- IP whitelist enforcement (src/auth/whitelist.rs)
- Job manager with async operation support
- WebSocket streaming for job status

Phase 3: Security Hardening
- Security testing: 16/16 tests passing
- Fuzz testing: 21 tests, all findings resolved
- Threat model validation (STRIDE matrix)
- TLS binding fix (critical vulnerability resolved)
- Security documentation complete

Phase 4: Production Readiness
- Performance benchmarking (all targets met)
- Package creation (.deb/.rpm structures)
- Documentation (README, API docs, deployment guide)
- Security hardening (6 vulnerabilities fixed)

Deliverables:
- API_DOCUMENTATION.md (889 lines)
- DEPLOYMENT_GUIDE.md (733 lines)
- SECURITY.md (346 lines)
- README.md (525 lines)
- debian/ package structure
- linux-patch-api.spec (RPM)
- install.sh installer script
- benches/api_benchmarks.rs
- Multiple security/performance reports

Security Status: 0 vulnerabilities remaining
Test Coverage: 31 unit tests, 21 integration tests
Build Status: Release optimized
