ListOpts now exposes a Type string field (TypeAny / TypeTask /
TypeProject). TypeAny is the new way to express "both tasks and
projects" in a single ListWorkspaces call -- which the next two
commits will use to consolidate cmd/last and cmd/delete onto a
single helper, and to make 'ctask list' default to showing both
types.
Invalid Type values now return an explicit error from
ListWorkspaces (defensive against typos in callers).
cmd/list, cmd/last, and cmd/delete are migrated to the new field.
External behavior is unchanged in this commit; the cleanup of
ctask list semantics happens in a follow-up commit so the diff
stays reviewable.
