Triage analysis

This issue is a post-release cleanup task involving reverting CI/workflow configuration files and removing v1.0.0 references. This is clearly a maintenance/refactoring task rather than a bug or new feature.

• It's about cleaning up config files → maintenance
• No actual bug, no user-facing feature, just housekeeping → low priority → priority: low

gh issue edit --add-label "maintenance,priority: low"
