Make NodeIds0-5 and StatusCodes0 classes public

[Copilot]

Scala cannot access inherited static members from package-private parent classes. This prevented Scala code from importing NodeIds0, StatusCodes0, etc. directly as a workaround.

fixes #1686

Changes

• Changed visibility of NodeIds0 through NodeIds5 from package-private to public abstract
• Changed visibility of StatusCodes0 from package-private to public abstract

Usage

Scala code can now import these classes directly:

import org.eclipse.milo.opcua.stack.core.NodeIds0
import org.eclipse.milo.opcua.stack.core.StatusCodes0

// Access constants from the parent classes
val booleanNodeId = NodeIds0.Boolean
val goodStatus = StatusCodes0.Good

This enables Scala developers to work around language limitations while maintaining the existing Java API unchanged.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Make inherited NodeIds0 and StatusCodes0 public visibility</issue_title>
<issue_description>See #1685 (comment), where apparently these constants can't be accessed from Scala as-is, and the solution would be to import NodeIds0, NodeIds1, StatusCodes0, etc... directly, but the current package-private visibility prevents it.</issue_description>

<agent_instructions>All the inherited NodeIdsN classes and the StatusCodes0 class should be public visibility instead of package-private.</agent_instructions>
