test(e2e): align keyless expectations with the shipped config and scope keys

The acp escalation smoke advertises the shipped deepseek-v4-pro; the
workspace-context e2e asserts the per-candidate scope key. The PTY harness
drops COLORTERM (deterministic banner) and gains configArgs/prepare/inspect
for the dsh CLI scenarios.
