There was a problem hiding this comment.
I wonder if we can reduce line count in this file, either by adding some .T or by turning off linting selectively.

Summary
Following #306 and #307, this PR adds local Clifford twirling. This can be enabled by setting the new
twirling_groupargument of thegenerate_preset_pass_manageror thegroupargument of theTwirlannotation tolocal_c1.Details and comments
A lot of the building stage is forward looking to support RZZ twirling.
As the two-qubit entanglers are Hermitian, there is a single local C1 subgroup. For non-Hermitian gates, we can do the same thing but would need different subgroups for left- and right-dressed boxes.
I used Claude Ops 4.6.
