- process.py: stop context_id engines in the inner finally block, before
restore_gd() wipes _py_func_contexts/_lua_func_contexts from the global
dict — engines were previously orphaned after every test run
- py_func/tm.py: add user-facing docstrings to gd/setgd/delgd; remove
internal JSON-serialization details from the docs
- helper_lib.rst: auto-generate global variable helpers from py_func.tm
(the actual subprocess API) instead of globdict
- conf.py: add src/ to Sphinx sys.path so py_func.tm is importable
- py_func_test_item.rst: simplify context sharing section, remove
JSON-serializable/non-serializable distinction for end users
- Regenerated PDF manual
