0.2.4

[Timwood0x10]

v0.2.4 (2026-07-24)

Windows compilation stability — fully static-linked codescope.exe (zero MinGW runtime DLLs), LadybugDB disabled on Windows (SQLite-only), and critical cross-compilation bug fixes.

🚀 New Features

• Fully static Windows binary: codescope.exe statically links libstdc++, libgcc, and libwinpthread via .cargo/config.toml -static rustflag. Zero MinGW runtime DLL dependencies at runtime — no more libstdc++-6.dll / libgcc_s_seh-1.dll / libwinpthread-1.dll version conflicts. (engine/CMakeLists.txt, server/build.rs)
• Dev branch CI for Windows: New .github/workflows/dev.yml validates Windows cross-compilation on push to dev branch (manual workflow_dispatch also supported). (dev.yml)

🐛 Bug Fixes

• Cross-compile host OS detection: build.rs previously used CARGO_CFG_TARGET_OS to detect the build host, but during cross-compilation this returns the target OS ("windows"), causing -DCMAKE_SYSTEM_NAME=Windows to never be passed to CMake. Fixed to use std::env::consts::OS for the actual build host. (server/build.rs)
• Cross-compile compiler selection: platform_default_compiler("windows") returned gcc/g++ on macOS, which resolves to native clang, not the MinGW cross-compiler. Fixed to detect cross-compilation and use x86_64-w64-mingw32-gcc/x86_64-w64-mingw32-g++. (server/build.rs)
• Stale LadybugDB CMake cache on cross-compile: The shared build-release/ directory retained LadybugDB cache entries from a previous native macOS build. When cross-compiling to Windows, the stale macOS .dylib path was passed to the MinGW linker. Fixed by unset(LADYBUG_LIBRARY CACHE) in the Windows CMake branch and a Rust-side guard that skips all LadybugDB cache reading on Windows. (engine/CMakeLists.txt, server/build.rs)
• LadybugDB now skipped on Windows: The vendored lbug_shared.lib is a static archive of unverified MinGW ABI with no corresponding .dll. Windows builds now compile with HAS_LADYBUG undefined and use SQLite as the sole graph store. (engine/CMakeLists.txt)

🧹 Chores

• Version bump: 0.2.3 → 0.2.4
• Windows support now explicitly documented as "beta" in both README.md and README.zh.md.
