Description

As an OCM developer I want to base my controller rework on an existing component version resolution service I can call safely.

• Design LRU cache with singleflight + semaphore worker pool
• Define cache key generation (canonical JSON + SHA-256)
• Add cache invalidation strategies (event-driven, TTL, negative caching)
• Integrate metrics (cache hit/miss, queue size, worker pool usage)

Described conceptually by https://github.com/open-component-model/open-component-model/blob/main/docs/adr/0009_controller_v2_lib_migration.md

This should be based on the new OCM Libraries and make use of the component version repository abstraction there.
