0579303602 feat: allow setting custom Session on ListingDatabase (#2526)
## Summary

Add support for providing a custom `Session` when connecting to a
`ListingDatabase`. This allows users to configure object store
registries, caching, and other session-related settings while
maintaining full backward compatibility.

## Usage Example

```rust
use std::sync::Arc;
use lancedb::connect;

let custom_session = Arc::new(lance::session::Session::default());

let db = connect("/path/to/database")
    .session(custom_session)
    .execute()
    .await?;
```

88283110f4 fix: handle input with missing columns when using embedding functions (#2516)
## Summary

Fixes #2515 by implementing comprehensive support for missing columns in
Arrow table inputs when using embedding functions.

### Problem
Previously, when an Arrow table was passed to `fromDataToBuffer` with
missing columns and a schema containing embedding functions, the system
would fail because `applyEmbeddingsFromMetadata` expected all columns to
be present in the table.

087fe6343d test: fix random data may break test case (#2514)
this test adds a new vector and then performs vector search with
distance range.
this may fail if the new vector becomes the closest one to the query
vector

ab8cbe62dd fix: excessive object storage handle creation in create_table (#2505)
This fixes two bugs with create_table storage handle reuse. First issue
is, the database object did not previously carry a session that
create_table operations could reuse for create_table operations.

Second issue is, the inheritance logic for create_table and open_table
was causing empty storage options (i.e Some({})) to get sent, instead of
None. Lance handles these differently:

* When None is set, the object store held in the session's storage
registry that was created at "connect" is used. This value stays in the
cache long-term (probably as long as the db reference is held).
* When Some({}) is sent, LanceDB will create a new connection and cache
it for an empty key. However, that cached value will remain valid only
as long as the client holds a reference to the table. After that, the
cache is poisoned and the next create_table with the same key, will
create a new connection. This confounds reuse if e.g python gc's the
table object before another table is created.

My feeling is that the second path, if intentional, is probably meant to
serve cases where tables are overriding settings and the cached
connection is assumed not to be generally applicable. The bug is we were
engaging that mechanism for all tables.

f076bb41f4 feat: add support for returning all scores with rerankers (#2509)
Previously `return_score="all"` was supported only for the default
reranker (RRF) and not the model based rerankers.
This adds support for keeping all scores in the base reranker so that
all model based rerankers can use it. Its a slower path than keeping
just the relevance score but can be useful in debugging

4c999fb651 chore: fix cleanupOlderThan docs (#2504)
Thanks for all your work.

The docstring for `OptimizeOptions ` seems to reference a non-existent
method on `Table`. I believe this is the correct example for
`cleanupOlderThan`.

This also appears in the generated docs, but I assume they live
downstream from this code?

167fccc427 fix: change 'return' to 'raise' for unimplemented remote table function (#2484)
just noticed that we're doing a 'return' instead of a 'raise' while
trying to get remote functionality working for my project. I went ahead
and implemented tests for both of the unimplemented functions (to_pandas
and to_arrow) while I was in there.

```ts
maximumNprobes(maximumNprobes): VectorQuery

Set the maximum number of probes used.
This controls the maximum number of partitions that will be searched. If this
number is greater than minimumNprobes then the excess partitions will _only_ be
searched if we have not found enough results. This can be useful when there is
a narrow filter to allow these queries to spend more time searching and avoid
potential false negatives.

parameter will impact every query against a vector index, regardless of the
filter. See `nprobes` for more details. Higher values will increase recall
but will also increase latency.

# LanceDB Java SDK
## Configuration and Initialization
### LanceDB Cloud
For LanceDB Cloud, use the simplified builder API:
```java
import com.lancedb.lance.namespace.LanceRestNamespace;
// If your DB url is db://example-db, then your database here is example-db
LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
.apiKey("your_lancedb_cloud_api_key")
.database("your_database_name")
.build();
```
### LanceDB Enterprise
For Enterprise deployments, use your VPC endpoint:
```java
LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
.apiKey("your_lancedb_enterprise_api_key")
.database("your-top-dir") // Your top level folder under your cloud bucket, e.g. s3://your-bucket/your-top-dir/
.hostOverride("http://<vpc_endpoint_dns_name>:80")
.build();
```
## Development
Build:
```shell
./mvnw install
```
