Issue-113. feat: add @TmsLink support and @Artifact annotations.

[GolubNick]

Summary

This PR introduces several improvements to the Testomat Java ecosystem:

Added

Allure @TmsLink Support

Added support for resolving Test IDs from Allure @TmsLink annotations in the Testomat Allure Adapter.

The adapter now automatically extracts the TMS identifier from:

@TmsLink("AUTH-001")

when no explicit @TestId annotation is present.

@Artifact Annotation Support

Added support for automatic artifact attachment using the @Artifact annotation.

Supported return types:

• String
• Path
• File

Example:

@Artifact
public Path attachScreenshot(Path screenshot) {
    return screenshot;
}

Artifacts can be attached at both:

• Test level
• Step level (when executed inside a @Step method or active step)

Documentation

• Updated README structure and content
• Added @Artifact usage examples
• Added step level artifact examples
• Improved documentation readability and consistency
• Removed obsolete and duplicated sections

Tests

• Added unit tests for AllureTmsLinkAspect
• Added unit tests for AllureTmsResolver
• Added unit tests for ArtifactAspect
