## Issue
Closes#5552
## Change
`MongoDbMetadataFilterMapper.map()` had no branch for the core filter
type `ContainsString`, so it fell through to the default branch and
threw `UnsupportedOperationException`. Sibling stores (milvus, pgvector,
azure-cosmos-nosql) already handle it; this closes that parity gap.
Added a `ContainsString` branch before the default `else`, plus a
`mapContains` method that renders `Filters.regex(metadata.<key>,
Pattern.quote(value))`.
`ContainsString.test()` uses `str.contains(value)`, a literal substring
check. `Pattern.quote(...)` escapes the value so regex metacharacters
(`.`, `*`, `(`) match literally, matching milvus's `LIKE %value%`
semantics.
Where this runs: `ContainsString` is not a `$vectorSearch` pre-filter.
It is applied in the post-search `$match` aggregation stage in
`MongoDbEmbeddingStore.search()` and in `removeAll(Filter)`'s
`deleteMany`. Both are ordinary query contexts that support `$regex`
(per MongoDB docs), so the fix is valid at runtime.
Scope: the new branch, `mapContains`, and two imports, plus two
spotless-ratchet reformats of pre-existing lines in the touched file
(long `throw` wrap, a stray space) required for `spotless:check` to
pass.

## Issue
Closes [#4105](https://github.com/langchain4j/langchain4j/issues/4105)
## Change
Since 5.6.0 Mongo driver added support for dynamic client metadata
For this change:
1. Upgraded mongo-client version to 5.6.0
2. Added langchain4j to driver name to Client Metadata in
MongoDbEmbeddingStore, spring boot already does it
[here](c687998f56/module/spring-boot-mongodb/src/main/java/org/springframework/boot/mongodb/autoconfigure/MongoClientFactorySupport.java (L62))
, however for spring boot `MongoClient` created as a bean but
`MongoDbEmbeddingStore` accepts `MongoClient` from the client , so the
append happens within `MongoDbEmbeddingStore` constructor
3. Added integration test to verify client metadata
4. The call to `appendMetadata` is dynamic so that clients with older
driver versions can still use it

## Change
- Added `maven-flatten-plugin` to `langchain4j-parent` and
`langchain4j-bom`
- Removed integration-specific dependencies from `langchain4j-parent`'s
`dependencyManagement` section and moved them to the modules where these
dependencies are used
- Explicitly added missing implicit dependencies
- Removed redundant `<maven.compiler.release>` for cassandra, infinispan
and opensearch modules
- Removed redundant license declarations and outdated properties

## Issue
Cleanup repeating dependencies in pom.xml. Better test assertions and
apidocs/javadoc generation.
## Change
Refactor project structure and remove unused test dependencies.
- Repeating test dependencies like `tinylog`, `awaitility` and others
were removed from various modules and consolidated in the parent module.
This reduction in clutter helps to streamline the testing process.
- A separate `kotlin` profile was created to manage Kotlin-related
configurations and dependencies.
- Upgraded versions of dependencies like `ai-mocks` and `wiremock` were
implemented. Moved to wiremock-standalone (shaded jar) to avoid
potential version conflicts with runtime classes.
- The test changes in `ChatRequestExtensionsTest.kt` partially migrated
from AssertJ to Kotest assertions.
- Updated Dokka plugin configuration

## Change
This pull request includes the following changes to improve project
dependency management:
- Removed unnecessary and redundant Netty dependencies and exclusions.
- Updated and reorganized dependency versions for consistency, including
new BOM imports for Azure SDK, Netty, and Reactor.
- Eliminated AWS SDK v1 dependencies, transitioning to
`software.amazon.awssdk` BOM for better compatibility and reduced
clutter.
- Removed redundant test dependencies like `assertj-core` and `mockito`
across modules, referring to the parent POM.
- Adjusted `kotlinx-coroutines-test` to use JVM-specific artifact and
standardized dependency version variables.
- Refined POM XML formatting for consistency and clarity (`mvn
spotless:apply`)
