## Summary
- Added `TarBz2` variant to `AssetKind` enum for `.tar.bz2` / `.tbz2`
archives
- Implemented `extract_tar_bz2` using the `bzip2` feature of
`async-compression` (already a workspace dependency, just enabled the
feature flag)
- Wired up both streaming and file-based extraction paths in
`github_download.rs`
- Added `.tar.bz2` / `.tbz2` URL detection in both
`LocalExtensionArchiveAgent` and `LocalRegistryArchiveAgent`
This unblocks ACP registry entries (like Goose) that only ship
`.tar.bz2` archives.

## Test plan
- [ ] Verify `cargo check` and `clippy` pass (confirmed locally)
- [ ] Test downloading an ACP agent that ships a `.tar.bz2` archive
(e.g., Goose)
- [ ] Verify existing `.tar.gz` and `.zip` agent downloads still work
Release Notes:
- Added support for `.tar.bz2` archives in ACP agent server downloads,
unblocking registry entries like Goose that only ship bzip2-compressed
tarballs.
