Add OSGi Metadata Generation

[konczdev]

Motivation and Context

Added OSGi metadata generation support using the bnd-maven-plugin to enable proper OSGi bundle creation. This change allows the SDK to be used in OSGi environments while maintaining compatibility with regular Java applications. The generated metadata includes:

• Proper bundle naming and versioning
• Explicit package exports with versions
• Optional dependencies for Jakarta
• Version ranges for required dependencies
• Java 17 capability requirement

How Has This Been Tested?

• Verified MANIFEST.MF generation with Maven build
• Validated package exports and imports with correct versions

Breaking Changes

No breaking changes. This enhancement is completely backwards compatible:

• Non-OSGi users are unaffected
• Existing Maven builds continue to work as before
• No API changes or runtime behavior modifications

Types of changes

• New feature (non-breaking change which adds functionality)

Checklist

• I have read the MCP Documentation
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have added or updated documentation as needed

Additional context

The implementation uses bnd-maven-plugin 7.1.0 for metadata generation.
