chore: prepare v2.0.0 release

- Update version to v2.0.0 in ApiConstants.java and bridge_mcp_hydra.py
- Create CHANGELOG v2.0.0 section with release date
- Fix Ghidra 11.3.2+ compatibility in TransactionHelper (endTransaction signature)
- Clarify instances_list vs instances_discover usage in documentation
- Remove commented-out code in pom.xml

Fixes #7
Closes #5
