Fix macOS multiprocessing compatibility

[Elymaro]

On macOS, MANSPIDER uses the spawn multiprocessing start method. The file parser process receives a bound Spiderling.parse_file method, which requires the Spiderling instance to be pickled. This instance contains an Impacket SMBConnection, whose SMB3 state contains non-picklable objects such as local lambda functions, resulting in a PicklingError.

Replacing the parser subprocess with a thread avoids serializing the active SMB connection while preserving asynchronous parsing.

Additionally, spawned child processes recreate MANSPIDER's multiprocessing logging queue without starting a corresponding QueueListener, causing console logs to disappear while file logging continues to work.
