Tag a Symfony cache pool directly as the memory cache adapter, remove MemoryAdapter #89

Description

cleverage/cache-process-bundle#67 (PR cleverage/cache-process-bundle#68, next 2.x minor) lets an application tag a Symfony cache pool service with cleverage.cache.adapter directly: the bundle wraps it in its Adapter, no adapter class is needed anymore.

The demo still declares the memory adapter through a custom class, App\Adapter\MemoryAdapter (an Adapter around an ArrayAdapter), used by the demo.cache.* and demo.transformers_edge.cached processes.

Proposed fix

• Replace the app.cleverage_cache_process.adapter.memory service by a cache pool declared with parent: cache.adapter.array, tagged cache.pool and cleverage.cache.adapter (code memory).
• Remove src/Adapter/MemoryAdapter.php, update .claude/CLAUDE.md which points to it.
• Once the cache bundle is released, require its new minor and update composer.lock: with 2.2, a pool tagged directly fails (it does not implement the bundle's AdapterInterface).
