azdev v0.2.13

• azdev extension add / azdev setup: regenerate *.egg-info after the editable install so development extensions stay discoverable. --no-build-isolation (0.2.12) means pip no longer leaves an *.egg-info in the source tree, which made azdev extension add a silent no-op for discovery. (#554)
• azdev extension build: depend on wheel so setup.py bdist_wheel works even when the environment's setuptools predates the bundled bdist_wheel command (< 70.1). Modern, unpinned wheel for building only; does not restore the wheel==0.30.0 metadata pin removed in 0.2.12b1.
• azdev extension build: surface the underlying setup.py output on build failure instead of re-raising an opaque CalledProcessError.
