feat(cli): add setup-renderdoc command for one-step install (#181)

* feat(cli): add setup-renderdoc command for one-step install

* refactor(doctor): simplify _make_build_hint to single return

All three platform branches returned identical text after the
setup-renderdoc unification.  Collapse to a single return.

* fix(doctor): check RENDERDOC_PYTHON_PATH and skip stale vulkan entries

- _check_win_python_version: include RENDERDOC_PYTHON_PATH in search
  paths so pixi-local installs are found
- _check_win_vulkan_layer: collect all registry entries and pick the
  first one whose JSON file actually exists, instead of failing on a
  stale entry from a previous install

* fix(docs): add setup-renderdoc to commands.json category
