Breaking changes

• Nedelec → Nedelec{kind}: replace Nedelec() with nedelec (= Nedelec{1}()) or nedelec2 (= Nedelec{2}()).
• DivConforming abstract type removed: RaviartThomas and BDM now directly subtype ReferenceFEName.
• CellFE constructor: trailing positional args are now keyword args.
• SignFlipMap, TransformRTDofBasis, TransformNedelecDofBasis removed: handled internally by the new Pullbacks.jl pipeline.
• ReferenceFE(name, args...; kwargs...) now returns a tuple (name, args, kwargs) instead of directly constructing a RefFE.
• Default polynomial bases changed: internal representations differ from v0.19 — affects serialised data and exact numerical values.
• ThirdOrderTensorValue is now a type alias for HighOrderTensorValue. Code relying on type identity may break.
• MacroReferenceFE constructor gains a 3rd positional argument Name.
• Conformity(reffe, sym::Symbol) per-element overloads removed: custom elements must implement valid_conformity_symbols instead.
• FineToCoarseReferenceFEs.jl no longer loaded.
• Old stubs apply, FETerm, AffineFETerm, LinearFETerm, FESource, FEEnergy removed from the Gridap namespace.

New features

• Polynomials: new Chebyshev and Bernstein polynomial types; new CartProdPolyBasis and CompWiseTensorPolyBasis generalising the old monomial bases; new high-level factory FEEC_poly_basis covering all spaces in the Periodic Table of the Finite Elements.
• ReferenceFEs: new ReferenceFE(F, r, k[, T]; kwargs...) constructor using FEEC notation; new MomentBasedReferenceFE factory unifying moment-based element construction; new elements modal_lagrangian, modal_serendipity, CrouzeixRaviart, and nedelec2; unified Piola map hierarchy (Pullbacks.jl) and geometric decomposition API.
• TensorValues: new SkewSymTensorValue and HighOrderTensorValue types; new operations congruent_prod, contracted_product, and component_basis.
• Default bases and quadratures: simplex elements (RT, BDM, Nédélec) now use Bernstein bases by default; n-cube elements use Legendre.
