Refactor type annotations and error handling in core modules

Standardize error message extraction to handle non-Error objects. Add explicit return types and interface definitions to VaultIndexer. Update SemanticCacheService to use any types where necessary. Rename SemanticCache to SemanticCacheService and adjust imports.
