`maintained_indexes` on a MemWAL table has three values: a named list, `[]` for none, and `null` for every index the table has, including ones created later. This PR makes every client read all three back as they were set. - **Rust remote client** (also used by the Python and Node SDKs) reads `null` as `None`. - **Java client** reads `null` as `null`, not as an empty list. - **Docs** for the setter, the field and the getter describe the three values the same way in Rust, Python, Node and Java. The generated JS docs are regenerated to match. ## Testing - `rust/lancedb`: 73 LSM tests pass, including one case per value. With the decoder typed as a list, the `null` case fails. - Java: two cases for `null` and `[]` on the read path, run by the Java CI job. - `cargo fmt`, `cargo clippy -D warnings` and `ruff format` are clean.
