use named logger, drop force=True

[avinxshKD]

Replaced root logger config with logging.getLogger('concore') + NullHandler(). The force=True was nuking any logging setup done before importing concore, which breaks apps using it as a library

Changed all logging.info/error/warning/debug calls to use the named logger instead.

Fixes #410

hey @pradeeban noticed this while poking around the codebase (quick fix)

While looking at this I also noticed a few other py/cpp/java inconsistencies along the same lines (type mismatches, default handling etc). Happy to audit those too or if there's a higher-priority area you'd rather I dig into first, just point me there. I would love your suggestions (just like you trained me how to tackle merge conflicts lol)

Don't worry too much about the inconsistencies at this point. There are many.
