Restore release LZFSE packaging command

[Augani]

Root cause

The accelerated dory-hv refactor removed the streaming LZFSE codec and CLI route, but scripts/bundle-engine.sh still uses the signed runner as the release compression authority. Public release assembly therefore failed at the first guest kernel with dory-hv: unknown command lzfse.

Fix

• restore the runner-owned streaming LZFSE codec
• restore dory-hv lzfse compress|decompress
• validate missing inputs explicitly
• add a multi-chunk round-trip regression test

Verification

• swift test --package-path Packages/ContainerizationEngine --filter LZFSETests
• 5 MiB runner-to-Apple compression_tool decode compatibility
• 5 MiB Apple compression_tool-to-runner decode compatibility
• direct CLI round trip
• python3 .github/scripts/test-release-orchestrator.py
• bash -n scripts/release.sh scripts/bundle-engine.sh
• git diff --check
