set_spending_policy

Adjust the agent-side spending policy (perTxCapUsd, sessionCapUsd, autoApproveUnderUsd; each 0-10 USD). Fields that are lowering (or unchanged) apply immediately via agentSetPolicy, independent of what happens to any raise in the same call. Fields that are raising ask the human via an approval sheet — if approved, that consent also lifts the human baseline (not just a one-off agent allowance), since going through the sheet IS the human path. If declined (or another approval sheet is already open), any lowering fields from this call stay applied and the result is `{ok:false, denied:'human_declined_or_busy', applied: }` — retry the raise after the sheet clears.
