feat(install): Windows Service wrapper for headless DNS failover

[louzt]

Summary

Add a Windows Service wrapper so DNS failover runs as a native Windows Service, surviving restarts and running without a logged-in user.

Changes

New files

File	Purpose
	Entry point — calls Windows Service module
	ServiceMain handler, STOP control handler, DNS Intel lifecycle
	+ recovery options + start
	after stopping

Modified files

• : Added (Windows-only dep) and binary entry
• • : Added Windows Service usage section

Dependencies

• — stable, minimal (~150KB binary impact)
• feature added to existing crate

Binary

• — builds on Linux (stub main), runs on Windows only
• — unchanged, still for Linux systemd users

Testing

• ✅
• ✅ (Linux stub)
• → 6/6 tests pass

Note: Cannot test Windows Service on Linux. Service tested manually on Windows VM after build.

Summary by CodeRabbit

• New Features

  • Added Windows DNS Failover Service support, including a new service binary and installer/uninstaller scripts.
  • The service can now be installed, started, checked, and removed from Windows using PowerShell.

📝 Walkthrough

Walkthrough

Adds a Windows service implementation for the netboozt DNS failover feature. Includes a new netboozt-service Rust binary with a Windows SCM-integrated runner, two PowerShell scripts for install/uninstall, updated Cargo dependencies, and corresponding documentation sections in both English and Spanish READMEs.

Changes

Windows DNS Failover Service

Layer / File(s)	Summary
Rust service binary and Windows runner platforms/tauri/src-tauri/Cargo.toml, platforms/tauri/src-tauri/src/bin/netboozt-service.rs, platforms/tauri/src-tauri/src/bin/windows_service/mod.rs	Adds windows-service = "0.6" and Win32_System_Services to Cargo deps, defines the netboozt-service binary target, implements the main entry point with a non-Windows fallback, and provides the Windows SCM runner that starts DNS intelligence on a thread, handles Stop via an atomic flag, and transitions service status through Running → StopPending.
PowerShell management scripts platforms/tauri/scripts/install-windows-service.ps1, platforms/tauri/scripts/uninstall-windows-service.ps1	Install script enforces Admin privileges, validates binary path, removes any existing netboozt-dns service, creates it via sc.exe create with auto-start and failure recovery, starts it, and verifies status. Uninstall script checks Admin, stops and deletes the service via sc.exe delete with exit-code validation.
Documentation README.md, README.es.md	Adds Windows DNS Failover Service sections in both READMEs covering build, install, status check, and uninstall commands.

Poem

🐰 Hop hop, the service is set,
On Windows it runs — no worries yet!
sc.exe create, a flick of the paw,
DNS failover without a flaw.
Install or uninstall, quick as a wink,
This rabbit's got services faster than you'd think! 🎉
