Description

We should have a setup so that way the DAE initialization algorithm's default tolerances match those from solve. That would require a setup for delayed tolerance changes.

Contributor guide

Research direction
Inspect the DAE initialization code in OrdinaryDiffEq.jl to understand current tolerance handling, then implement a mechanism to delay tolerance changes to match those from solve.
