chore(python): pyproject no longer claims the wheel vendors agent-context

hatch_build.py has been a no-op since agent-context scaffolding moved to
the Node `meta agent-docs` CLI, but pyproject.toml still described it
copying ../../agent-context into the package and forced a gitignored
`_content/**` tree into both artifacts. That glob matched nothing. The
comment now says what is true, the dead `artifacts` line is gone, and the
FR-033 note sits on the wheel target it describes (without its stale
file count).

Verified with uv build: the wheel still carries the committed
spec_metamodel JSON, and no _content.
