Fix multi-line handling for all workflow outputs

- Updated all GitHub Actions output syntax in claude-full.yml for consistent multi-line handling
- Ensured all steps use the same heredoc-style EOF delimiter approach
- Applied consistent pattern for all PR and issue comment handling sections
- Fixed PR review sections that were previously missed

This addresses the workflow validation errors and ensures consistent handling of multi-line feedback throughout the action.
