fix: sanitize hardcoded build-machine paths in standalone output (#147)

Next.js standalone bakes absolute build-time paths (outputFileTracingRoot,
appDir, turbopack root) into server.js and required-server-files.json.
When installed via npm on a different machine, these paths don't exist,
causing ENOENT errors. The prepublish script now replaces build-machine
absolute paths with '.' (relative) so they resolve correctly wherever
the package is installed.
