.SYNOPSIS
    Build the Windows installer: Electron client + bundled Python node.

.DESCRIPTION
    The Windows counterpart of packaging/build/build-client.sh. Produces a
    single per-user NSIS installer (MeshBay-Setup-<version>.exe) that lays down
    the Electron app and, beside it under resources/node-runtime/, the frozen
    meshbay-node daemon. No hub -- a desktop machine installs client + node
    (+ common, which is inside the node runtime).

    This is the "Full" target. See build-win-light.ps1 for "Light" (client +
    UI only, no bundled node) -- steps 1-4 below live in build-win-common.ps1,
    shared by both, so they cannot drift apart.

    Steps:
      1. Node >= 22 check
      2. npm ci  (+ approve Electron's install script, download Chromium)
      3. bump Electron to the latest release  (Chromium CVE policy -- see
         build-client.sh; skip with -NoElectronBump)
      4. npm run sync-ui        (copy the interface from the hub package)
      5. build-node-runtime.ps1 (PyInstaller freeze of the daemon) -- Light
         skips this step entirely, which is the whole difference
      6. electron-builder --win nsis

.PARAMETER SkipFfmpeg
    Passed through to build-node-runtime.ps1 -- skip bundling ffmpeg (fetched
    and verified by default; see fetch-ffmpeg.ps1). Smaller, streaming-less
    build for local iteration only.

.PARAMETER NoElectronBump
    Keep the pinned Electron instead of upgrading to the latest release.

.PARAMETER SkipNodeRuntime
    Reuse an existing packages/meshbay-client/node-runtime/ (faster iteration
    on the electron-builder side).
