+         * Enhanced signal handling for AWS Batch tasks to fix nested Nextflow execution issues.
+         * This implementation addresses the problem of proper signal forwarding when Nextflow
+         * processes are executed within AWS Batch containers.

+         * References: https://github.com/nextflow-io/nextflow/pull/6414
+         * 
+         * Trap command breakdown:
+         * 
+         * 1. TERM signal trap: `trap \"[[ -n \\\$pid ]] && kill -TERM \\\$pid\" TERM`
+         *    - Captures SIGTERM signals sent to the parent shell process
+         *    - Conditionally forwards the TERM signal to the background bash process (stored in $pid)
+         *    - The `[[ -n \\\$pid ]]` test ensures we only attempt to kill if $pid is set and non-empty
+         *    - This prevents attempts to kill process ID 0 or empty values, which could cause unintended behavior
+         *    - Essential for proper cleanup when AWS Batch terminates jobs or when users cancel workflows
+         * 
+         * 2. EXIT signal trap: `trap \"{ ret=\$?; $aws ${TaskRun.CMD_LOG} ${workDir}/${TaskRun.CMD_LOG}||true; exit \$ret; }\" EXIT`
+         *    - Executes cleanup actions when the shell process exits (normal or abnormal termination)
+         *    - Captures the exit status ($?) of the last executed command before cleanup
+         *    - Uploads the command log file to S3 for debugging and monitoring purposes
+         *    - Uses `||true` to prevent the trap from failing if S3 upload fails (ensures exit code preservation)
+         *    - Preserves and returns the original exit status to maintain proper error propagation
+         * 
+         * 3. Background execution pattern: `bash > >(tee ${TaskRun.CMD_LOG}) 2>&1 & pid=\$!; wait \$pid`
+         *    - Runs the actual task command in background (&) to allow signal handling
+         *    - Redirects both stdout and stderr (2>&1) to process substitution for real-time logging
+         *    - Uses `tee` to simultaneously write logs to file and display to console
+         *    - Stores the background process ID in $pid for signal forwarding
+         *    - `wait $pid` ensures the parent shell waits for task completion and returns proper exit code
+         *    - This pattern allows the parent shell to remain responsive to signals while task executes
