## Issue
Closes#5672
## Change
`GcsSource` built its metadata by calling `metadata.put("contentType",
blob.getContentType())`. `Blob.getContentType()` is nullable, and core
`Metadata.put(String, String)` rejects null with an
`IllegalArgumentException`. Loading a valid, non-empty object without a
content type therefore failed: `loadDocument()` threw, and
`loadDocuments()` caught the exception and silently skipped the object.
This change skips the `contentType` key when `getContentType()` returns
null, so the key is absent rather than holding a meaningless `"null"`
string. The sibling `AzureBlobStorageSource` already guards its metadata
(via `String.valueOf`); this brings the GCS loader in line. Scope is
limited to the `contentType` line.
Added `GcsSourceTest` with a Mockito-mocked `Blob`: a regression case
(null content type builds successfully, key absent) and a positive case
(`text/plain` preserved).

## Issue
Closes#4326
## Change
Added exception handling to skip failed documents in
`AzureBlobStorageDocumentLoader.loadDocuments()` and
`GoogleCloudStorageDocumentLoader.loadDocuments()`, matching the
behavior of `AmazonS3DocumentLoader` and `TencentCosDocumentLoader`.
- Added try-catch blocks to skip failed documents and log warnings
- Updated Javadoc to document skip behavior

## 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`)

## Issue
Adds format consistency check for changed files. Closes#2109
## Change
- Add [Spotless Maven plugin](https://github.com/diffplug/spotless) for
code java (eclipse java format) and pom.xml formatting
- Added the `<project.root.dir>` property across multiple POM files to
standardize the directory structure reference. This ensures consistent
project configurations and reduces redundancy in defining the root
project directory. Adjusted existing XML formatting minimally to
accommodate the new property integration.
- Cleanup duplicate settings in pgvector module
- Updated pom.xml files were reformatted according to
[defaults](https://github.com/diffplug/spotless/tree/main/plugin-maven#sortpom)
+ 4 spaces
- Adding linting and formatting commands to the `Makefile`, updating the
`pom.xml` files for better project configuration, and enhancing the
`CONTRIBUTING.md` guidelines.
