26080ee4c1 feat: add prewarm_index function (#2342)
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **New Features**
- Added the ability to prewarm (load into memory) table indexes via new
methods in Python, Node.js, and Rust APIs, potentially reducing
cold-start query latency.
- **Bug Fixes**
- Ensured prewarming an index does not interfere with subsequent search
operations.
- **Tests**
- Introduced new test cases to verify full-text search index creation,
prewarming, and search functionalities in both Python and Node.js.
- **Chores**
  - Updated dependencies for improved compatibility and performance.

1ee63984f5 feat: allow FSB to be used for btree indices (#2297)
We recently allowed this for lance but there was a check in lancedb as
well that was preventing it

## Summary by CodeRabbit

- **New Features**
- Added support for indexing fixed-size binary data using B-tree
structures for efficient data storage and retrieval.
- **Tests**
- Implemented automated tests to ensure the new binary indexing works
correctly and meets the expected configuration.

e70fd4fecc feat: support IVF_FLAT, binary vectors and hamming distance (#1955)
binary vectors and hamming distance can work on only IVF_FLAT, so
introduce them all in this PR.

91cab3b556 feat(python): transition Python remote sdk to use Rust implementation (#1701)
* Replaces Python implementation of Remote SDK with Rust one.
* Drops dependency on `attrs` and `cachetools`. Makes `requests` an
optional dependency used only for embeddings feature.
* Adds dependency on `nest-asyncio`. This was required to get hybrid
search working.
* Deprecate `request_thread_pool` parameter. We now use the tokio
threadpool.
* Stop caching the `schema` on a remote table. Schema is mutable and
there's no mechanism in place to invalidate the cache.
* Removed the client-side resolution of the vector column. We should
already be resolving this server-side.

33b402c861 fix: list_indices returns correct index type (#1715)
Fixes https://github.com/lancedb/lancedb/issues/1711

Doesn't address this https://github.com/lancedb/lance/issues/2039

Instead we load the index statistics, which seems to contain the index
type. However, this involves more IO than previously. I'm not sure
whether we care that much. If we do, we can fix that upstream Lance
issue.

f958f4d2e8 feat: remote index stats (#1702)
BREAKING CHANGE: the return value of `index_stats` method has changed
and all `index_stats` APIs now take index name instead of UUID. Also
several deprecated index statistics methods were removed.

* Removes deprecated methods for individual index statistics
* Aligns public `IndexStatistics` struct with API response from LanceDB
Cloud.
* Implements `index_stats` for remote Rust SDK and Python async API.
