fix(cips): Clarify sampling window vs pruning window

[renaynay]

Sampling window (light nodes sampling blocks) = 30 days
Pruning window (full nodes storing and serving blocks) = 30 days + 1

Question:
Should we make clear definitions in the CIP to differentiate pruning window from sampling window?

small changes. re:

I think adding definitions of "Sampling window" and "Pruning window" into the Specification would be beneficial.

thanks @renaynay - what do you think about adding to the specs section?

Sampling window (light nodes sampling blocks) = 30 days
Pruning window (full nodes storing and serving blocks) = 30 days + 1

@jcstein pls take a look at 3d3cc5b
