/**
* Acts on a resolved session-limit continuation answer.
*
* Granted: bumps the runtime token limits via
* {@link bumpSessionRuntimeUsageLimits} and lets the step continue
* transparently.
* Declined: a user decision, not an error — the decline cancels the
* in-flight turn tree through the standard cancellation path, settling as
* `turn.cancelled` → `session.waiting` with no failure surfaced anywhere.
* The harness only declares the intent by throwing
* {@link SessionLimitDeclinedError}; the execution layer detects it at the
* step boundary and cancels the root turn, whose cancelled arm cascades to
* every descendant, so the delegating parent never receives an error result
* it could retry against a fresh budget share.
*
* Returns `result: null` when the step should continue with `session`.
