Why

The code example on the home page was Python only, even though lance-csr also ships as a Rust crate. Rust readers had to go to another page to see what the same query looks like in Rust.

What changed

• The home page example now has Python and Rust tabs. Each tab has its own code block, so the copy button copies the code in the tab that is showing.
• The Rust tab matches the Python example: the same three Person rows and two KNOWS edges, held in memory with EngineSource::Arrow, and the same [:KNOWS*1..2] query, which returns Bob and Carol.
• As the docs guidelines require, the Rust code lives in a new quickstart section of the embedded_query example rather than in the page, so CI compiles and runs it. The tab shows only the body of the code, without its use lines, the same way the Rust guide does.

There are no API or behaviour changes. The only user-facing changes are the home page and the runnable example.

Validation

• uv run --project docs --locked zensical build --strict: no issues. The built home page has both tabs and the Rust snippet.
• uvx typos@1.26.0 .: clean.
• docs/check_snippets.py against a local build: passes, including the Python block inside its tab.
• cargo run -p lance-csr --example embedded_query: prints Bob and Carol, which matches the output comment.
• cargo fmt --all -- --check and cargo clippy -p lance-csr --example embedded_query -- -D warnings: clean.
• No benchmarks: no engine code changed.
• I haven't tried the tabs or the copy button in a browser. CI is pending.
