Closes the two genuine gaps beyond task 10.1's own coverage (standby and
disconnected-scheduler rejection were already tested):
- Forward timeout: adds an XCE_TESTING-only timeout-override seam
(SCHEDADMIN_TIMEOUT_MS) in cluster.c, verified inert in production
builds (-DXCE_TESTING absent from xce_controller's target and every
project-wide arg; the non-test branch is a bare 5000L literal).
test_schedadmin_forward_timeout drives the real 5s (shrunk to 200ms
under test) pthread_cond_timedwait to genuine expiry and asserts the
exact {ok=false, error="request timeout"} shape from AC 10.
- Round-trip coverage: two more outcome-branch tests
(rpc_status_only, business_error) using the same real xce_encode/
xce_decode functions production uses. A literal two-binary
controller<->scheduler integration was judged out of scope (separate
meson targets, incompatible fixtures) since task 9.4's own
test_admin_request.c already white-box-drives the real scheduler
handler rigorously.
Controller suite 3/3 (1093/1093 assertions, up from 1090), scheduler
26/26 unaffected, clang-format clean, zero diff-hygiene noise (git diff
matches git diff -w for cluster.c).
