Rename directories:
AdGuard for Windows → AdGuard for Windows v7
AdGuard for Windows v8 → AdGuard for Windows

Move AdGuard for Windows v7 to ~Archive

Build and deploy / build (pull_request) and Build and deploy / build (push) are failed because of:

1. Non-existent /adguard-for-windows-v7/ prefix — archive index pages link to /adguard-for-windows-v7/features/home-screen/, /adguard-for-windows-v7/solving-problems/wfp-driver/, ~18 targets total. That route doesn't exist: the folder is archive/adguard-for-windows-7, and the target files were never moved there.

2. Missing v8 pages — protection/protection.md links to seven articles (ad-blocking, tracking-protection, annoyance-blocking, dns-protection, browsing-security, parental-control, extensions) and settings/settings.md links to license, support, about. None of these files exist in the branch — only the index pages were committed.

3. .md extension inside absolute links — e.g. /adguard-for-windows/settings/app-settings/filter-editor.md in app-settings.md, and five similar links in archive/adguard-for-windows-7/adguard-for-windows.md.
