T05 entry 4: wire consumer relations and refresh issue-core evidence.

Add supports/related_to for vergabe-teilnahme and activity-core, cite
SCOPE.md, update test count to 120 (verified), and document dual-canonical
relationship with CAPABILITY-issue-tracking.yaml.

 ## Overview
 
-`issue-core` is a universal interface for issue-tracking coordination across Gitea, GitHub, and GitLab, giving agents a unified Python API and CLI instead of direct platform API calls. This registry entry migrates the repo's own pre-existing `CAPABILITY-issue-tracking.yaml` capability manifest (109 tests, 61% coverage, documented usage rules and credential handling) into the standard `registry/capabilities/` location.
