…s, and take kernels - Port the onpair encoding to the onpair 0.1.0 public API (raw column parts, validated dictionaries, MaxDictBits config). - Add compressed-domain LIKE pushdown backed by onpair prefix/substring search, plus list_contains and take compute kernels. - onpair is temporarily a git dependency pinned to the 0.1.0 merge commit; it will switch to the crates.io release before this PR is marked ready for review.

Rationale for this change
onpair 0.1.0 (spiraldb/onpair#20) refactors the library into modules and adds compressed-domain search (equality, prefix, substring). This PR ports the OnPair encoding to the new API and uses the search entry points to evaluate
LIKEdirectly on compressed data instead of canonicalizing first.Note
Draft: onpair 0.1.0 is not yet published to crates.io, so the dependency is temporarily a git dependency pinned to the 0.1.0 merge commit (
spiraldb/onpair@a31dfd5). It will be switched to the crates.io release before this PR is marked ready for review. The immediate goal is to run the SQL benchmarks and measure the impact of LIKE pushdown.What changes are included in this PR?
vortex-onpairand the btrblocks OnPair string scheme to the onpair 0.1.0 API (raw column parts, validatedCompactDictionaryView,MaxDictBitsconfig).like(equality/prefix/substring patterns, backed by onpair's compressed-domain search),list_contains, andtake.Cargo.toml/Cargo.lock: onpair 0.0.4 → 0.1.0 (temporary git pin, see note above).Checks run locally:
cargo nextest run -p vortex-onpair(43 tests passing),cargo check -p vortex-onpair -p vortex-btrblocks,cargo +nightly fmt --all, and clippy — all clean.What APIs are changed? Are there any user-facing changes?
No public Vortex API changes. Behavior change:
LIKE,list_contains, andtakeon OnPair-encoded arrays are now evaluated in the compressed domain instead of falling back to canonicalization.
