fix: java init stuck in main and param parser broken for values with =

[avinxshKD]

Fixes #424

moved init (iport, oport, params, maxtime) from main() into a static {} block so the class actually initializes on load
replaced the broken replaceAll("=", "':'") fallback with a proper

• parseParams() that splits on first = only mirrors
• concore_base.parse_params

Hey @pradeeban the old fallback was doing replaceAll("=", "':'") which nukes every = in the value... so something like url=https://x.com?a=1 turns into {'url':'https://x.com?a':'1'} and literalEval rightfully throws. split on first = only fixes it, same way parse_params in python already handles it. also moved init out of main() since nobody calls main() when importing the class from another file.

Let me know if you want changes in this file or any other Java parts. Goodnight

@avinxshKD Java implementation was mostly just a toy. No wonder it was buggy.
