This PR adds initial support for using DifferentiationInterface.jl backends (ADTypes) as the sensealg parameter for computing derivatives of integrals. Changes: - Add IntegralsDifferentiationInterfaceExt extension that defines a ChainRulesCore.rrule for __solvebp when sensealg is an AbstractADType - Add ADTypes and DifferentiationInterface as weak dependencies - Add compat bounds for ADTypes (1) and DifferentiationInterface (0.6) This provides the foundation for using unified AD backends like AutoZygote(), AutoForwardDiff(), etc. as sensealg instead of the current ReCallVJP(ZygoteVJP()) wrapper. Note: Full integration testing is TODO - the extension needs further refinement to work seamlessly with the existing Zygote/Mooncake extensions. This is an initial implementation that addresses issue SciML#258. Closes SciML#258 Co-Authored-By: Claude Opus 4.5 <[email protected]>

Why the outdated version @ChrisRackauckas?

Sounds like a dangerous way to add new features?

Not documenting it for now because we can't run half of the ADs on v1.12 right now 😅
