Type inconsistency: excludePaths is defined as optional in AppChatContextSchema but required in ContextPathResults, breaking the type contract and potentially causing TypeScript compilation issues.

excludePath is supplied as an include path, so excluded files are incorrectly treated as included ones, giving wrong results (Based on your team's feedback about catching logical errors that stem from incorrect property usage).
