Detailed Description

Creates and caches Vulkan samplers (Singleton)

Samplers control how textures are filtered and addressed when sampled in shaders. This factory caches samplers based on configuration to avoid creating duplicates.

Lifecycle:

• Initialize with backend reference
• Create samplers via get_or_create()
• Samplers are cached and reused
• Cleanup destroys all samplers

Thread-safe after initialization.
