AssetManager is a singleton that loads, caches, and manages the lifetime of shared engine assets. Phase 1.3 adds support for TaskGraphTemplate assets:

• LoadTaskGraph() : load from file (or return cached entry) -> AssetID
• GetTaskGraph() : retrieve a cached template by AssetID
• UnloadTaskGraph() : release a cached template from memory

Asset IDs are 32-bit FNV-1a hashes of the normalised file path so that the same path always yields the same ID without requiring a central registry.

Ownership: AssetManager owns all loaded TaskGraphTemplate instances via unique_ptr. Callers receive a raw pointer (non-owning) from GetTaskGraph(). The pointer remains valid until UnloadTaskGraph() or ~AssetManager() is called.

C++14 compliant - no std::variant, std::optional, or C++17/20 features.
