feat(cache): enable repo cache for all Packagist API calls

Remove the Option wrapper from repo_cache in ResolveRequest,
LockFileGenerationRequest, and fetch_package_versions. All commands
now initialize a Cache via build_cache_config(cli.no_cache), ensuring
Packagist metadata is cached to disk (respecting --no-cache flag).
