Subject: [PATCH] Discover sample packages instead of listing them
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hatchling's `packages` setting takes literal paths and does not accept
patterns, so the wheel target listed every sample by hand. That list drifted:
an entry naming a directory that does not exist is ignored without a warning,
so `nexus` (added in #174, where the directory was actually `hello_nexus`)
never matched anything, and 14 sample directories added since the uv migration
were never shipped — including `google_adk_agents` and `openai_agents`. The
sdist shipped no samples at all.

Switch to setuptools, whose `packages.find` discovers them declaratively, so
adding a sample requires no build config change. Namespace discovery is needed
because some samples have subdirectories without an `__init__.py`.

Verified: the wheel and sdist each contain exactly the 652 tracked sample .py
files (the wheel previously had 405 from 33 hand-listed entries; the sdist had
none), with no venv, cache, or lambda_worker content; a wheel install and an
editable install both import samples the old list omitted; the AI sample tests
pass against the reinstalled editable project.
