task/bulk close: hardcoded status 'complete' fails on lists with differently named done status

[timimsms]

Context

cu task close and cu bulk close set the task status to the hardcoded string "complete". ClickUp statuses are per-list and user-defined, so on any list whose done/closed status has a different name (e.g. "Done", "Closed", "Shipped"), the close command fails with an API error.

Evidence

• internal/cmd/task.go:402-407 (TODO at 404):

// Find a closed status in the same list
// For now, we'll use "complete" as the closed status
// TODO: Query the list's statuses to find the actual closed status
updateOpts := &api.TaskUpdateOptions{
	Status: "complete",
}

• internal/cmd/bulk.go:209 — bulk close has the same hardcoded Status: "complete".

Suggested fix

Resolve the list's actual closed status before updating: fetch the task's list statuses (list detail includes statuses[] with type fields) and pick the status with type == "closed" (or "done" as fallback). Apply the same resolution in both task close and bulk close, and cover it with a test using a list whose closed status is not named "complete".
