The .py extractor runs fine under PyGhidra in the GUI; only `analyzeHeadless`
doesn't init PyGhidra. Add an env-gated CPython path so modern Ghidra works headless:
- ghidra.run_extractor_pyghidra(): runs the same GhidraScript via pyghidra.run_script
(boots Ghidra in-process, imports+analyses, getScriptArgs()=[out_path]); run_extractor
dispatches to it when AMS_USE_PYGHIDRA is set. No script changes needed.
- worker image installs pyghidra + sets GHIDRA_INSTALL_DIR; compose exposes
AMS_USE_PYGHIDRA (default off). Jython path stays the default and untouched.
- README documents both variants (Jython <=11.3.x vs PyGhidra 11.4+/12.x).
- test: AMS_USE_PYGHIDRA routes to the PyGhidra back-end (clear error if pkg missing).
35/35 tests pass.
