Introduced `SearchIndexDefinition` sealed interface with factory methods,
`VectorSearchIndexFields` (`vectorField`, `filterField`, `autoEmbedField` builders),
`HnswSearchIndexOptions` for HNSW-specific parameters, and
`VectorSearchIndexDefinition` as the concrete implementation.

Added Scala companion objects for `SearchIndexDefinition` and
`VectorSearchIndexFields` with delegating factory methods, and a
`SearchIndexModel.apply` overload for `VectorSearchIndexDefinition`.

Annotated mutable builders with `@NotThreadSafe`. Added fail-fast
null-element validation using notNullElements in factory methods.

Includes unit tests (Java) and spec tests (Scala).

Adds builder support for the $rerank pipeline stage (MongoDB 8.3, Atlas only).

API:
- RerankQuery: query object with text shorthand or full Bson for future modalities
- Aggregates.rerank(): 2 overloads (single path, multi path)
- Scala wrappers and type alias in Aggregates.scala

This change fixes the TLS channel stream connection-establishment path so address resolution happens before opening a SocketChannel. Previously, TlsChannelStream opened and configured a SocketChannel before calling getSocketAddresses. If the configured resolver failed, the exception was reported to the async handler, but the already-opened channel was not closed.

Resolving the address before opening the channel avoids the resolver-failure leak and aligns TlsChannelStream with the existing async socket-channel and Netty stream implementations. The setup path now also closes the channel if any pre-registration step fails after the channel has been opened.

The micrometer-observation dependency is optional but its packages were
imported as required in the OSGi metadata, causing bundle resolution
failure in OSGi containers.

Adds io.micrometer.*;resolution:=optional to driver-core Import-Package.

Also adds a new testing/osgi-test module that uses Apache Felix to verify
all driver bundles resolve without optional dependencies present. This
runs in CI via static-checks.sh to prevent future regressions.

…a driver (mongodb#1986)

* Add BinaryVector and VectorSearchQuery vectorSearch overloads to Scala driver

The Scala Aggregates wrapper only exposed the `Iterable[Double]` overload of
vectorSearch. This adds the `BinaryVector` (since 5.3) and `VectorSearchQuery`
auto-embedding (since 5.7) overloads. Changes the existing overload's parameter
from `Iterable[java.lang.Double]` to `Iterable[Double]` to resolve Scala type
inference ambiguity when multiple overloads are present.

Also fixes scaladoc warnings for unresolvable cross-module Java type links.
