refactor(python): launch the minimal example through sdk-minimal

Make minimal.py select the shipped sdk-minimal profile directly and pass its selected model into the profile-owned adapter catalog. The Python SDK still starts only the bundled dsh CLI with an explicit Harness home; it no longer supplies an invocation overlay for this mode.

Drive both the source keyless process test and installed-wheel smoke through the same named profile. The keyless test pins the generated profile manifest and exact two-tool model request, while the packaged smoke keeps the persistent-shell, editor, session-log, and model-visible snapshot evidence.

Delete minimal.patch.yml and the unused complete-config/replay fixtures. Their composition now has one owner in @deepseek-ai/dsh-sdk-minimal, so the example and tests cannot drift into separate launch trees.
