REM Opencode JetBrains Plugin Build Script
REM Supports building two variants:
REM   - Standard:  bundles opencode binaries (default)
REM   - GUI-only:  no binaries, uses system opencode, embeds webgui-dist
REM
REM By default both variants are built. Use --gui-only or --standard-only to
REM build a single variant.
