Yang Cen 7abc57a4d0 test: cover refined RQ queries after deferred compaction (#4839)
Add SDK coverage for a refined IVF_RQ7 query after deferred compaction
with physical row addresses. The test combines deletion and
prefiltering, verifies the retained index UUID and actual FRI metadata,
requires an ANN plan, and compares IDs/distances before and after
compaction plus recall against a flat oracle.

This is a test-only change on main with the released Lance beta.10
dependency adopted by #4838. It adds no production behavior or
dependency changes. Sophon lazy-executor adoption and integrated
performance acceptance remain separate.

Validation on macOS ARM64 with pinned Rust 1.97.0:

- Five focused SDK regressions passed (0.15 s test runtime), covering
deferred FRI compaction/refinement, stable row IDs, ANN approximation
mode and large query limits.
- `cargo clippy --locked --features remote --tests --examples -- -D
warnings` passed.
- Formatting and diff checks passed.

The native test linker emitted a macOS compact-unwind size warning; all
cases completed successfully without linker-setting changes.
