> [spark-connect-rust] Faster Connect parity CI (ours-only + skip manifest) and
> 100% Rust coverage

> The Connect parity gate runs all 84 official connect test files twice each
> (reference pyspark AND our client via transport injection) against one live
> server, ~1h20m-2h. Now that the client is at full parity, the reference run
> only serves to compute a per-file environmental-failure baseline.
> h2. Changes
> * Parity gate: run ONLY our client against the official connect suite,
> deselecting a checked-in per-test manifest of known environmental failures
> (tests the reference client also fails in this single-node pure-Connect CI
> env, each annotated with the reason). Drops the reference run, roughly
> halving CI/build time. The manifest is regenerated from a reference run when
> the Spark version bumps.
> * Add in-repo Rust tests (plan-building golden + e2e_integration) covering
> the functionality behind the env-skipped official tests, so skipping them
> loses no real coverage.
> * Enforce 100% Rust test coverage across all crates (spark-connect-core,
> spark-connect, and the pyspark-rs PyO3 layer measured via the Python suite
> driving an instrumented extension) via a cargo-llvm-cov CI gate; fill the
> gaps with unit/integration tests.
