Never release a library before you've actually used it yourself, to avoid immediate breaking changes like this one.

### Added

- New `Metadata` struct to ensure the hash is always available, even on a failed lookup.

### Changed

- `Database.get_metadata()` and `Database.get_metadata_from_hash()` now return `Metadata` rather than `Option<Program>`.

### Removed

- Removed `Program.lookup_hash` property in favor of `Metadata.hash`.
