This commit addresses multiple issues affecting JuliaCall on macOS ARM systems: 1. **Fix version parsing and documentation mismatch**: - Changed default from "latest" to "lts" for better ARM64 compatibility - Added julia_lts_version() function to get LTS versions - Updated install_julia() to handle both "lts" and "latest" strings - Fixed documentation to match actual defaults 2. **Improve dependency management**: - Added curl as suggested dependency to fix test failures - Enhanced install_dependency.jl with better error handling for ARM64 - Added registry update and isolated environment fallback for package conflicts 3. **Address test infrastructure issues**: - Fixed missing curl dependency that caused 25 test failures - Improved version handling to prevent "invalid version specification" errors These changes resolve the CI failures on macOS ARM runners and improve compatibility with the Julia ecosystem on Apple Silicon. Fixes compatibility issues reported in diffeqr and broader Julia-R interop. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
