## Summary by CodeRabbit
- **Chores**
- Updated dependency management to use published crate versions for
improved reliability and maintainability.
- Added a temporary workaround for build issues by pinning a specific
version of a dependency.
- **Refactor**
- Improved resource management and concurrency by updating internal
ownership models for object storage components.

This PR fixes build issues associated with `aws-lc-rs`, while
simplifying the build process. Previously, we used custom scripts for
the musl and Windows ARM builds. These were complicated and prone to
breaking. This PR switches to a setup that mirrors
https://github.com/napi-rs/package-template/blob/main/.github/workflows/CI.yml.
* linux glibc and musl builds now use the Docker images provided by the
napi project
* Windows ARM build now just cross compiles from Windows x64, which
turns out to work quite well.
Support hybrid search in both rust and node SDKs.
- Adds a new rerankers package to rust LanceDB, with the implementation
of the default RRF reranker
- Adds a new hybrid package to lancedb, with some helper methods related
to hybrid search such as normalizing scores and converting score column
to rank columns
- Adds capability to LanceDB VectorQuery to perform hybrid search if it
has both a nearest vector and full text search parameters.
- Adds wrappers for reranker implementations to nodejs SDK.
Additional rerankers will be added in followup PRs

Notes about how the rust rerankers are wrapped for calling from JS:
I wanted to keep the core reranker logic, and the invocation of the
reranker by the query code, in Rust. This aligns with the philosophy of
the new node SDK where it's just a thin wrapper around Rust. However, I
also wanted to have support for users who want to add custom rerankers
written in Javascript.
When we add a reranker to the query from Javascript, it adds a special
Rust reranker that has a callback to the Javascript code (which could
then turn around and call an underlying Rust reranker implementation if
desired). This adds a bit of complexity, but overall I think it moves us
in the right direction of having the majority of the query logic in the
underlying Rust SDK while keeping the option open to support custom
Javascript Rerankers.
