Add portable executable deployment options (no Docker required)

[Copilot]

Analyzed and documented four approaches to deploy NOP as standalone executables without Docker, addressing the need for portable deployment across Windows/Linux/macOS.

Documentation Delivered

Decision Guides:

• PORTABLE_SOLUTION_RECOMMENDATION.md - Direct answers: use Nuitka for 1-2 week turnaround, server-client for teams, Go rewrite for long-term product
• PORTABLE_VISUAL_SUMMARY.md - ASCII architecture diagrams and decision flowcharts
• PORTABLE_EXECUTABLE_QUICK_START.md - Comparison matrix and getting started paths

Technical Analysis:

• PORTABLE_EXECUTABLE_SOLUTIONS.md - Complete architecture, code examples, and implementation steps for all options
• PORTABLE_BUILD_GUIDE_NUITKA.md - Step-by-step: PostgreSQL→SQLite migration, Redis→MemoryCache, Nuitka compilation, cross-platform builds

Four Options Analyzed

Option	Timeline	Size	Use Case
Nuitka	1-2 weeks	200-400MB	Quick portable, pen testing, USB deployment
Tauri	2-4 weeks	80-150MB	Professional desktop app with auto-updates
Server-Client	1-3 weeks	300MB+50MB	Multi-user SOC/NOC deployments
Go Rewrite	4-6 months	30-60MB	Commercial product, maximum performance

Recommended Path

Phase 1 (Week 1-2): Nuitka single executable - 95% code reuse, embedded SQLite/cache/frontend
Phase 2 (Week 3-4): Optional Tauri wrapper - native installers, auto-update
Phase 3 (Month 2-6): Optional Go migration - production-grade quality

Example Nuitka build structure:

# Single executable contains:
# - FastAPI backend (Nuitka-compiled)
# - SQLite database (embedded)
# - In-memory cache (Python dict + TTL)
# - React frontend (StaticFiles)
# - Platform-specific guacd binaries

app.mount("/", StaticFiles(directory="frontend_build", html=True))
DATABASE_URL = "sqlite+aiosqlite:///./nop.db"
cache = MemoryCache()  # Replaces Redis

All migration code, build scripts, and troubleshooting guides included. Ready for implementation.

Original prompt

Please go throughall branches we already worked on single portable exe for our application stack, and propose unified solution that we can make ( should we use nuitka to pack backend databases guacd into single exe and use browser to acess? Should we separate server and client and make client integrated in singke exe? What is best, give also few options not only one exe must work on any system and must work without docker
