 * Task Management CLI
 *
 * Usage: npx ts-node task-cli.ts <command> [feature] [args...]
 *
 * Commands:
 *   status [feature]              - Show task status summary
 *   next [feature]                - Show next eligible tasks
 *   parallel [feature]            - Show parallelizable tasks ready to run
 *   deps <feature> <seq>          - Show dependency tree for a task
 *   blocked [feature]             - Show blocked tasks and why
 *   complete <feature> <seq> "summary" - Mark task completed
 *   validate [feature]            - Validate JSON files and dependencies
 *
 * Task files are stored in .tmp/tasks/ at the project root:
 *   .tmp/tasks/{feature-slug}/task.json
 *   .tmp/tasks/{feature-slug}/subtask_01.json
 *   .tmp/tasks/completed/{feature-slug}/
