* fix: make release manifest parsing forward-compatible Unknown future platform entries in the release manifest no longer cause valid known binary entries to be discarded. The parser now skips unknown platforms while keeping strict validation for known ones (duplicates, bad filenames, bad sha256 still reject). Client-facing manifests (beta.json / latest.json) now advertise only the four legacy platforms (darwin-arm64, darwin-x64, linux-arm64, linux-x64) so pre-fix clients are not bricked by the new musl and baseline archive entries. All eight archives remain built, checksummed, and present in SHA256SUMS for the installer. * fix: publish versioned binary manifests
