- The
relativevalue is the weighted sum of the differences with weight given by the inverse of the current value of the statistic. - The
absolutevalue is therelativevalue divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

This PR constructs pasting for left lifts and shows the pasting lemma for (abs) left kan lifts. This is done for all four notions of left/right lifts/extensions.
This is needed for the oo-cosmos project.
AI disclosure. Claude was used in defining the API for the left lift case. After manually fixing its bad proofs/definitions/docstrings, Claude was later asked to replicate this for the other three cases, which I again finetuned.
