Subject: [PATCH] build(gateway): use @discordjs/opus prebuilt instead of
 compiling from source

Drop npm_config_build_from_source=true so node-pre-gyp downloads the
published prebuilt .node for Node 22 (ABI node-v127, linux-x64-glibc-2.35)
instead of compiling libopus C++ every build. Replace the hardcoded
'npm run install' (node-gyp compile) loop with 'pnpm rebuild @discordjs/opus'
which runs the package's own install script (prebuilt fetch, source build
only as fallback). sharp already uses @img prebuilt packages (its install
script failure is non-fatal), so only opus was actually compiling.
