 * supi_tndm_cli — thin wrapper around the tndm CLI.
 *
 * Actions map to tndm subcommands:
 *   create     → tndm ticket create <title> [--status] [--priority] [--type] [--tags] [--depends-on] [--effort] [--content]
 *   update     → tndm ticket update <id> [--title] [--status] [--priority] [--type] [--tags] [--add-tags] [--remove-tags] [--depends-on] [--effort] [--content]
 *   show       → tndm ticket show <id> --json
 *   list       → tndm ticket list [--all] [--definition <state>] --json
 *   awareness  → tndm awareness --against <ref> --json
 *   task_add       → tndm ticket task add <id> --title <title> --json, optionally followed by task detail ensure + sync when task_detail is provided
 *   task_list      → tndm ticket task list <id> --json
 *   task_complete  → tndm ticket task complete <id> <number> --json
 *   task_remove    → tndm ticket task remove <id> <number> --json
 *   task_edit      → tndm ticket task edit <id> <number> [--title] --json, optionally followed by task detail ensure/clear
 *   task_set       → tndm ticket task set <id> --tasks <json> --json
 *   doc_create and sync are internal operations used by flow tools, not exposed here.
