Summary

• Prepare repository-local internal Go requirements at the CDS project version before release; reuse module/workspace selection from tagging and preserve replacements and unrelated metadata.
• Add plugin guide landing pages and a Go multi-module guide, plus news fragments.
• Cover workspace resolution, replacements, semantic import versions, idempotence, and release integration with offline Go fixtures.

Verification

• 290 tests passed, 227 subtests passed ($env:PYTEST_DISABLE_PLUGIN_AUTOLOAD=1; python -m pytest -o addopts='' tests -q).
• Black and git diff --check passed.

Limitations

• Go major-version module path/import migrations remain manual; incompatible requirements fail before edits.
• Requirements without repository-local replace or workspace resolution are left unchanged. Existing beta tagging does not commit preparation changes.
