* make clippy happy

* minor test edits

* documentation corrections

* improve angle canonicalization test

* lint fix

* Restructuring the Clifford+T code: fully separating Clifford+T compilation
from the standard (near-term) compilation.

* tuning of Clifford+T pipeline

* fix to CircuitData vs PyCircuitData after merge-with-main

* update to loop condition + ruff

* Updating equivalence library with better decompositions of T/Tdg gates in terms of each other

This also required adding Z = Sdg Sdg (in addition to the existing Z = S S).

* Tuning Clifford+T pipeline

The translation to Clifford+T now uses all Clifford+T gates, and the loop in
the optimization stage now optimizes Clifford+T circuits. The post-loop
contains translation to the ... (continued)
