chore: update lance dependency to v13.0.0-beta.18 (#4339)

Updates the Rust workspace dependencies, Cargo lockfile, and Java
`lance-core` to [Lance
v13.0.0-beta.18](https://github.com/lance-format/lance/releases/tag/v13.0.0-beta.18).
It includes lance-format/lance#9574, which bounds the memory an IVF
partition split uses when it re-reads raw vectors during
`optimize_indices`, and lance-format/lance#9582, which keeps the mTLS
REST namespace client on rustls.

Lance's new combined-fields FTS query variant (introduced by
v13.0.0-beta.17) is handled the same way as in #4336: the remote
capability check and Rust/Node bindings accept it, with a regression
test for the remote request payload, and the Python conversion reports
that this query type is not yet supported. This PR supersedes #4336.
