feat(03-03): handle batch confirmation callback execution
- Update Parse Callback Data to detect batch (c is array) vs single - Add isBatch and containerIds fields to callback data - Add 'batch' route in Route Callback switch (output 2) - Add Build Batch Commands node to prepare curl commands for each container - Add Prepare Batch Execution to combine commands with result markers - Add Execute Batch Action to run all container actions sequentially - Add Parse Batch Result to parse RESULT_N:statusCode output - Add Format Batch Result to build success/failure message
