bug: Missing Error Handling in LocalFileMemoryProvider

[fazlerahmanejazi]

Problem

The LocalFileMemoryProvider.loadFacts() method throws an uncaught SerializationException that crashes the entire memory system when encountering corrupted JSON files.
Current code (line 154):

private suspend fun loadFacts(path: Path): Map<String, List<Fact>> = mutex.withLock {
    val content = storage.read(path) ?: return emptyMap()
    return json.decodeFromString(content)  // No error handling
}

Expected behavior:

Log the error and return empty map so the agent can continue running.

Impact:

• Agent crashes instead of continuing with valid memory data
• No logging to debug the issue
• Memory system becomes unusable until corrupted files are manually removed

Digging more into error handling, I noticed Koog is following fail fast policy.

This changes the behavior from "corrupted JSON fails agent execution" to "corrupted JSON gracefully degrades with empty results" - please confirm this aligns with your error handling philosophy!
