Fix: Use preprocess enriched output in generate-implementation

- Restore dependency on preprocess so generate-implementation runs after it
- Use enriched task from preprocess when available
- Fallback to issue title if preprocess skipped/failed
- All outputs come from prepare-task step to avoid skipped job output issues
