refactor(submodule): Update paths to ensure submodule integration

- Updated `Setup.mk` to point `BUILDER_DIR` to the new JMBuilder submodule directory (`vendor/JMBuilder`)
- Modified `retriever.py` to adjust JMBuilder path in `sys.path` and define `BUILDER_DIR` variable for proper integration
- Ensured that the project continues to run as expected with the JMBuilder submodule

These changes are crucial for maintaining project functionality after the JMBuilder migration to a submodule.
