v0.1.52 — Windows installation and help documentation

Make Windows setup and support instructions easier to find and follow.

• User Guide 3.20 adds native Windows installation, the four Setup choices, first sign-in, local-network access, camera setup order, portable backup, Linux-to-Windows migration, and UI-update acceptance.
• A new step-by-step Windows guide is linked from README, the installation/migration guides and GitHub issue chooser.
• The roadmap and compatibility/deployment pages now describe the shipped stable Windows installer and updater, with the actual validation scope preserved.
• The Community wiki provides installation, backup/migration and troubleshooting navigation while detailed instructions remain in the versioned repository guides.
• GitHub bug forms include native Windows 10 and Windows 11 options.

This is a documentation update. Database SQL, runtime dependencies and Windows maintenance/service code are unchanged from 0.1.51. Existing installations can update through Settings → Software Updates. Complete the displayed checks and select Accept update. Passwords, API key, records, images and settings carry forward with the normal recovery backup.

New Windows users should download the Windows-x64-Setup.exe asset and follow the Windows installation guide. The attached User Guide PDF is also available in the application under Help.
