giles 6f52cff0d9 W14: fix C22/K104 — harness logs IO before invoking the mock (+3 pins) ...

The interceptor appended the IO-log entry only after the mock returned, so
a throwing mock left no entry and error-path tests falsely reported "never
invoked" through assert-io-called/count (hosts.md C22, core.md K104).

spec/harness.sx make-interceptor now appends {:args :result nil :op}
BEFORE invoking the mock and updates :result in place via dict-set! on
return. This is W14-owned test infrastructure (PLAN.md W14 approach item
4), not a semantics edit.

Pins: suite gate-C22-throwing-mock-logged (throwing mock leaves an entry
with pending result; happy path updates the result; mixed throwing +
successful sequence counts all calls). Harness self-suite (15 tests) and
test-relate-picker (the only other harness consumer) verified green;
285/0 on the pins run.
