build: Move to pyproject + setuptools_scm0.23.0

Replace setup.py and MANIFEST.in with pyproject.toml. The version is
now derived from git tags via setuptools_scm, and added
.git_archival.txt and .gitattributes for git archive support. Remove
_version.py from version control as it is now auto-generated at build
time.

+## Versioning
+
+Rumba uses `setuptools_scm` to derive its version from git tags.
+
+**Compatibility contract across Ouroboros repositories:**
+
+| Scope | Rule |
+|---|---|
+| ouroboros (C) ↔ pyouroboros / rumba | Shared `major.minor` — rumba requires at least the same ouroboros `major.minor` |
+| pyouroboros ↔ rumba ↔ ouroboros-integration | Strict lockstep `major.minor.patch` — always released together |
