Statically link MinGW builds to eliminate DLL dependencies

[Copilot]

Releases built with MinGW depend on libwinpthread-1.dll and other runtime DLLs, requiring users to have MinGW installed.

Changes

• Added -static flag to MinGW linker options in CMakeLists.txt

The existing -static-libgcc -static-libstdc++ flags only covered GCC/C++ runtimes. The -static flag ensures complete static linking including winpthread.

if(NOT MSVC)
    target_link_options(legacy-notepad PRIVATE -mwindows -municode -static)
    target_link_libraries(legacy-notepad PRIVATE -static-libgcc -static-libstdc++)
    # ...
endif()

Result: Standalone exe with no MinGW dependencies. MSVC builds unchanged.

Pull request overview

This PR updates the MinGW (non-MSVC) build configuration to produce a fully statically linked Windows executable, eliminating runtime DLL dependencies like libwinpthread-1.dll for release artifacts.

Changes:

• Add -static to the MinGW linker flags for legacy-notepad builds.

-mwindows is already added via CMAKE_EXE_LINKER_FLAGS in the non-MSVC branch (line 13) and -municode is already added via add_compile_options (line 12). With the new -static flag, this block now duplicates flags and also mixes linker flags between target_link_options (line 46) and target_link_libraries (line 47). Consider keeping only -static in target_link_options and moving -static-libgcc/-static-libstdc++ into target_link_options as well (leaving target_link_libraries for actual libraries) to avoid confusing/fragile flag handling.
