 * Read-only execution budget validation (#328).
 *
 * Shared by every provider that implements `queryReadOnly`, so the agent
 * execution profile cannot end up with one provider validating its budget and
 * another trusting it. The check is fail-closed: the whole call is refused
 * unless every field is a positive integer in range.

 * The upper bound matters doubly on PostgreSQL, where the timeout is
 * interpolated into `SET LOCAL statement_timeout = N` (SET takes no bind
 * parameters), so nothing that is not a positive integer may reach it.
