Update ZigHouse
- Refresh c6i.4xlarge result with v0.2.0-clickbench binary - Bump install to v0.2.0-clickbench (SHA256 5c30c8e3...) - Add generic-smoke.sh demonstrating the generic SQL execution path (responds to feedback in #895 about hardcoded query handling)

The benchmark script downloads `hits.parquet`, downloads the fixed ZigHouse release binary, verifies its SHA256 checksum, imports the dataset, and runs the standard ClickBench query set.

## Two execution paths
22+
23+
- **ClickBench optimization profile** — fast paths hand-tuned to the shapes of the 43 ClickBench queries. Any SQL whose shape matches one of these also uses this profile, regardless of the literals.
24+
- **Generic SQL engine** — used for everything else, or when forced via `ZIGHOUSE_QUERY_PATH=generic`. `compare` mode runs both paths and checks byte-identical output.
25+
26+
`generic-smoke.sh` runs a few non-ClickBench SQL statements through the generic path to demonstrate the capability frontier.
