    ResolveLink Installer for DaVinci Resolve
    ==========================================
    Paste this into: Workspace > Console > Lua

    What it does:
    1. Detects your OS and checks for Git + Node.js
    2. Downloads the correct release version (or clones from repo)
    3. Runs the full setup (deps, build, extensions, .env)
    4. Deploys scripts and starts the server

    Install locations:
      Windows:  %LOCALAPPDATA%\ResolveLink
      macOS:    ~/Applications/ResolveLink
      Linux:    ~/.local/share/ResolveLink
]]

-- ============================================================
-- Release version (set by GitHub Actions at release time)
-- If this is "__RELEASE_TAG__", the installer clones from repo.
-- If it's a real tag like "v1.0.0", it downloads that release.
