Docker BuildKit exposes TARGET* for the requested image platform. It exposes
BUILD* for the daemon running build stages. The bootstrap path did not pass an
explicit platform or seed those args, so Dockerfile behavior could depend on daemon defaults.
Set the build request platform from TARGETPLATFORM when supplied. Use the daemon
platform as the fallback. Query the daemon for BUILD*. Seed implicit args without
overwriting caller values. Do not inject empty variant args.

Replace manual Header::set_path() + append() with
builder.append_path_with_name() which emits GNU LongName extensions
for paths exceeding the 100-byte POSIX tar name field limit.
