chore: 0.29.5 — parent_row provenance for blended row-transform functions

Also drops a now-genuinely-unused `# type: ignore[assignment]` on
table_function_plan's response (vgi/client/client.py:2395) — pre-existing
mypy failure (present since before this release, unrelated to parent_row),
cleared here since it was blocking every non-Windows CI leg for no reason
tied to this release. Windows CI's pre-existing socket.AF_UNIX failure in
test_launch_transport.py (also predates this release) is left alone per
this repo's "don't block on Windows CI" convention.
