Read the diff line by line: pure move plus the example_retargeters relative-import fix, no logic change.
Verified the install tree lands correctly at the stack tip (pyproject.toml at the example root, no doubled python/python/, no isaacteleop_examples/__init__.py), and python -m isaacteleop_examples.retargeting.sources_example --help runs from install/examples/retargeting/.

multi_retargeter_tuning_demo_imgui.py imported example_retargeters as a top-level module, which resolved only because the invoked script's own directory landed on sys.path -- so it broke under `python -m`, broke when copied into another project, and claimed the bare name `example_retargeters`. Move the tree to the layout in examples/README.md. Six co-equal demos, so no __main__.py: each is a submodule and the new README lists them. The example had no README before; the docs were the only place its scripts were named. The sharpa and wuji pages now open their command blocks with the install step, so each is runnable on its own rather than assuming a checkout layout. Part of #985.
