perf(pm): remove registry cache hook

[elrrrrrrr]

Summary

• remove the old RegistryClient::cache_version_manifest preload hook
• drop the now-unused UnifiedRegistry implementation of that hook
• keep manifest provider tests intact

Validation

• cargo fmt
• cargo check -p utoo-ruborist
• cargo test -p utoo-ruborist mock_registry_executes_manifest_provider_jobs -- --nocapture
• cargo test -p utoo-ruborist test_unified_registry_executes_extract_manifest_provider_job -- --nocapture
• cargo clippy --all-targets -- -D warnings --no-deps

Split Plan

Part of the resolver stack split from source PR #3028. This removes a preload-era cache callback before the registry memory-cache cleanup.

Code Review

This pull request removes the cache_version_manifest method from the RegistryClient trait and its implementation in UnifiedRegistry. I have no feedback to provide.
