list: 'cu list list' table output renders zero rows (type switch misses clickup.List)

[timimsms]

Context

cu list list renders an empty table in the default output mode, while -o json shows the expected lists. The table branch silently drops every row.

Evidence

• internal/cmd/list.go:57 — listListCmd accumulates results into var allLists []interface{}, appending typed clickup.List structs returned by client.GetLists(...).
• internal/cmd/list.go:121-141 — the table branch type-switches only on map[string]interface{}:

for _, item := range allLists {
	// Type assertion based on the actual type
	switch v := item.(type) {
	case map[string]interface{}:
		...
	}
}

Since every element is a clickup.List struct (not a map), no case matches, rows stays empty, and the table prints zero rows. JSON output works because it marshals the structs directly.

Suggested fix

Type-switch on clickup.List (or drop the []interface{} indirection entirely and use []clickup.List), and add a regression test that asserts cu list list table output contains the list rows.
