- Around line 166-169: Make prepareCatalog’s capture path safe during concurrent
reward loading by updating the rewards collection handling used by
RewardRegistry and PreparedRewardCatalog.capture. Prefer CopyOnWriteArrayList
for the rewards list, or create a synchronized snapshot while holding the list

The SHA-256 check detects corruption and version mismatches, but it does not prevent an actor who can rewrite the payload from recomputing the hash. If payloads remain in trusted durable storage, document this limitation in the Javadoc. If payloads cross an untrusted boundary, use a shared-secret MAC instead.

Summary
Adds an immutable, versioned snapshot API for resolved AdvancedCore reward definitions. A caller can capture a root reward and the current named reward registry, persist the encoded catalog alongside its own durable intent, and instantiate detached definitions after reload. Named lookup follows the registry's direct, sub-direct, then file precedence, including absent direct-handle shadows, and fails closed when a name was not captured. Reward capture coordinates with the full registry reload and sub-reward rebuild, bounds capture before retaining further definitions and bounds encoded record construction, and preserves raw file names for lookup precedence.
This is one prerequisite for the VotingPlugin shared vote-processing integration in BenCodez/VotingPlugin#1608. It adds no vote-specific classes and does not change the existing reward execution path. The caller remains responsible for using catalog lookups when building its prepared execution plan; existing native injectors still use their current lookup behavior. Detached instances cannot create legacy generated reward files.
