feat: add built_against field for ABI-sensitive dependencies

- Introduced a new field `built_against` in the InstalledPackageRecord struct to track concrete package names for ABI-sensitive dependencies.
- Updated database schema to include `built_against` column in the packages table.
- Modified package registration and listing functions to handle the new `built_against` field.
- Implemented helper functions to format and parse the `built_against` data.
- Enhanced tests to verify the correct handling of the `built_against` metadata during package registration and retrieval.
- Updated resolver logic to utilize `built_against` for dependency resolution.
