# Bash Wrapper for TypeScript Orchestrator
# Provides backward compatibility with bash-based orchestration
# Routes all calls to TypeScript implementation

# Usage:
#   ./orchestrate-ts.sh --task-id <id> \
#                       --mode <mvp|standard|enterprise> \
#                       --max-iterations <n>
