codename-206/deploy.ps1

<#
.SYNOPSIS
    Build Codename 206 and install the VST3 (and CLAP) into the system plugin folders.

.DESCRIPTION
    FL Studio scans `C:\Program Files\Common Files\VST3` by default and ignores
    directory junctions, so deployment must place a REAL bundle copy there. That
    folder needs admin, so the copy step self-elevates (one UAC prompt).

    After deploying, in FL Studio: Options -> Manage plugins ->
    tick "Rescan previously failed plugins" -> "Find installed plugins".

.PARAMETER SkipBuild
    Install the existing target\bundled output without rebuilding.

.PARAMETER User
    Install to the per-user folder %LOCALAPPDATA%\Programs\Common\VST3 instead of
    the global one. No admin required; add that path in FL's plugin search paths.

.EXAMPLE
    .\deploy.ps1                # build + install to global VST3/CLAP (UAC prompt)
    .\deploy.ps1 -SkipBuild     # reinstall last build
    .\deploy.ps1 -User          # no-admin install for a fast dev loop
#>
