Validate and adopt the S-CORE global toolchain configuration

[AlexanderLanin]

Background

The module_template provides a central S-CORE toolchain configuration intended to be shared across repositories.

At the moment, we do not know whether this configuration can be used by this repository as-is, or whether repository-specific additions are still required.

The goal of this issue is to adopt the central configuration unchanged, verify whether it works for this repository, and document any remaining gaps or differences.

Task

Integrate the S-CORE toolchain configuration from module_template into this repository and verify that the existing builds and tests continue to work.

The following central configuration must be used unchanged:

• the S-CORE Toolchains (DO NOT MODIFY) section from MODULE.bazel
• score.bazelrc/score_toolchain.bazelrc

Do not modify these definitions to make them fit this repository.

Instead, compare the central configuration with the toolchain configuration currently used by this repository.

For every difference, determine whether it is:

• missing from the central S-CORE configuration,
• intentionally repository-specific,
• no longer required, or
• already covered by the central configuration in a different way.

Any repository-specific configuration that is still required must be added separately from the central configuration.

Expected result

The repository uses the central S-CORE toolchain configuration unchanged.

The issue/PR should contain a short report describing:

• What works as-is with the central configuration.
• What is missing from the central configuration.
• What differs between the central configuration and this repository.
• What repository-specific configuration had to be added, and why.
• Any configuration that existed previously but could be removed because the central definition already provides it.

If something appears to be generally required for S-CORE rather than specific to this repository, document it as a candidate for moving into module_template.

Getting started

Use these files from module_template as the reference:

• MODULE.bazel
  https://github.com/eclipse-score/module_template/blob/main/MODULE.bazel
  Use the S-CORE Toolchains (DO NOT MODIFY) section unchanged.

• score.bazelrc/score_toolchain.bazelrc
  https://github.com/eclipse-score/module_template/blob/main/score.bazelrc/score_toolchain.bazelrc
  Use this file unchanged.

• .bazelrc
  https://github.com/eclipse-score/module_template/blob/main/.bazelrc

  Import the central toolchain configuration using:

  try-import %workspace%/score.bazelrc/score_toolchain.bazelrc
  

Acceptance criteria

• The S-CORE toolchain section from module_template/MODULE.bazel is used unchanged.
• score.bazelrc/score_toolchain.bazelrc is used unchanged.
• The central score_toolchain.bazelrc is imported from .bazelrc.
• Relevant repository builds/tests work with the resulting configuration.
• Repository-specific additions are kept separate from the central configuration.
• The PR documents central configuration gaps and repository-specific differences.
• Potential improvements to the central module_template configuration are identified.
