This commit makes the following changes: - Add Julia v1.11 to the CI testing matrix - Conditionally load Enzyme only on Julia versions < 1.12 - Define dummy types for EnzymeAdjoint and EnzymeVJP on v1.12+ that error if instantiated - Wrap Enzyme-specific method definitions in version checks - Make AutoEnzyme import conditional on Julia version Enzyme is currently incompatible with Julia v1.12, so this change ensures the package can still be used on v1.12 with other AD backends while maintaining full Enzyme support on earlier versions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Keep EnzymeAdjoint and EnzymeVJP types and exports always available. Only conditionally load `using Enzyme` on Julia < 1.12. The types will error with a clear message if instantiated on v1.12+. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
- Skip enzyme_closure.jl test entirely on v1.12 - Wrap EnzymeAdjoint gradient computations in concrete_solve_derivatives.jl - Wrap corresponding test assertions for Enzyme results 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
- Conditionally compile EnzymeVJP tests on Julia < 1.12 - Wrap InterpolatingAdjoint, QuadratureAdjoint, GaussAdjoint, and GaussKronrodAdjoint tests using EnzymeVJP - Wrap BacksolveAdjoint test with EnzymeVJP and its helper function 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]> EOF )

- Define ENZYME_ENABLED = VERSION < v"1.12" in SciMLSensitivity module - Export ENZYME_ENABLED for use in tests and downstream packages - Replace all @static if VERSION < v"1.12" with @static if ENZYME_ENABLED - Replace all if VERSION < v"1.12" with if ENZYME_ENABLED in tests - Makes it easy to change the Enzyme compatibility version in one place 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Enzyme is loadable on 1.12 always, so this isn't required atm

Summary
This PR makes Enzyme support conditional on Julia version < 1.12 and adds v1.11 to the CI testing matrix.

Enzyme is currently incompatible with Julia v1.12, so this change ensures the package can still be used on v1.12 with other AD backends (ForwardDiff, ReverseDiff, Zygote, Tracker, Mooncake) while maintaining full Enzyme support on earlier versions (v1.10, v1.11).
