GET /providers/claude-cli/status now returns an `acp` block:
{ enabled (experimental flag), bridgeAvailable (KTD10 published path), active
(enabled && acpEnabled && bridgeAvailable) } so operators can see whether Claude
CLI is routing through the ACP bridge vs `claude -p` — important for the
default-on rollout. Additive; typechecks clean.
