Pull request overview
Adds a “flow mode” to captain_utils.sh so interactive gum prompts can be driven non-interactively via a queued set of responses.
Changes:
- Introduces flow-mode infrastructure (
--flow) with wrappers forgum choose,gum confirm, andgum pager. - Replaces existing interactive prompts/pager usage with
flow_choose,flow_confirm, andflow_pager. - Adds a helm diff + confirmation step to the Calico upgrade path before applying changes.

Same concern here: eval "$helm_diff_cmd" | flow_pager relies on eval for command execution. Building the helm diff command as an argv array and executing it directly will be safer and remove the need for embedded quoting inside helm_diff_cmd.

--flow option parsing assumes a second argument exists. With set -u/set -e, running captain_utils.sh --flow (missing queue) will error via an unbound $2 and/or shift 2, instead of showing a helpful usage message. Add an explicit [[ $# -ge 2 ]] guard (and ideally validate non-empty) before reading $2 and shifting.

Flow queue parsing doesn’t trim whitespace around comma-separated values. A common input like --flow "1, 2,3" produces an element with a leading space (" 2"), which will fail the numeric validation later. Consider stripping spaces (e.g., remove whitespace after splitting, or set IFS=', ' with additional normalization) so flow mode is resilient to typical CLI formatting.
