chore: bump to 0.4.0rc0 for release pipeline smoke test (#12)

One-shot bump so we can tag v0.4.0-rc0 and verify the TestPyPI publish
flow end-to-end (OIDC trusted publisher, build, upload, install). The
rc0 slot on TestPyPI is a throwaway — it never goes to real PyPI and
doesn't conflict with any future v0.5.0 release plans.

After the smoke test verifies, main stays at 0.4.0rc0 until Phase 6
release prep bumps it forward to whatever the real release version is
(likely 0.5.0rc1).
