fix: resolve shell syntax errors in templates

- Remove problematic parentheses from echo statements that caused shell parsing errors
- Replace 'echo "text (with parens)"' with 'echo "text - with dashes"'
- All enhanced and advanced templates now pass shell syntax validation

Templates fixed:
- templates/enhanced/ai-to-telegram-simple.yaml
- templates/enhanced/opencode-poem-telegram-template.yaml

Syntax validation now passes for all 13 previously failing templates
