Rewrite all wiki pages to reflect the current CLI-complete, app-in-progress state Previous pages had drifted from reality (e.g. implying a more complete desktop app than exists, and missing several CLI subcommands added since). Every page is now grounded in the actual CLI --help output and gtavmm-core module docs.
Update docs: raw portable exe no longer shipped; add v0.16.2 to Changelog
Document the new Windows installer; add v0.16.1 to Changelog Getting Started, Building and Releasing, and User Manual now describe the installer (GTAV_Mods_Manager_Vx.x.x_setup.exe) as the recommended download, alongside the existing portable exe and framework-dependent zip.
Add Changelog and full User Manual pages - Changelog.md: compiled from all 24 GitHub Releases (v0.1.2 to v0.16.0), newest first, with download/SHA-256 sections preserved; notes that releases from v0.16.0 onward are auto-generated by the release workflow. - User-Manual.md: the complete docs/USER_MANUAL.md content ported as a single numbered tutorial page (24 sections, step-by-step, same structure as the topic-split pages but comprehensive and in one place). - Linked both from Home and _Sidebar.
