Add TensorAlgebraTensorKitSectorsExt for sector dual#215
Merged
Conversation
## Summary Adds a `TensorAlgebraTensorKitSectorsExt` extension defining `dual` on a TensorKitSectors sector (its charge conjugation). This is the sector-level companion to the TensorKit space `dual` and `isdual` overloads added in #214, keeping all overloads of TensorAlgebra generics on TensorKitSectors types in a dedicated extension. GradedArrays will drop its own sector `dual` in favor of this one.

…ys' own (#219) ## Summary GradedArrays now extends the `dual` and `isdual` generics owned by TensorAlgebra (added in ITensor/TensorAlgebra.jl#214) rather than defining its own copies, and re-exports them. Its `SectorRange`, `SectorOneTo`, and `GradedOneTo` methods become `TensorAlgebra.dual` / `TensorAlgebra.isdual` overloads. The `dual` on a raw TensorKitSectors sector moves to `TensorAlgebraTensorKitSectorsExt` (ITensor/TensorAlgebra.jl#215) and `dual` on a TensorKit `ElementarySpace` moves to `TensorAlgebraTensorKitExt`, so both are dropped here. Bumps the TensorAlgebra compat floor to 0.17.9.
