Windows release binaries (x86_64) via MSYS2/MinGW

Browse source 
Adds a windows-latest job to the release matrix: MSYS2/MinGW-w64 toolchain,
Chez 10.4.1 built from source (ta6nt), the same build-joltc flow, packaged
as a zip of joltc.exe. The whole job runs in the msys2 shell so cc/xxd/paths
behave; the produced binary is a plain Windows executable.

Platform seams: bld-nt? with the winsock/COM/registry link set, no -rdynamic
under MinGW, GetModuleFileName as the launcher's self-path on _WIN32, and
built binaries (joltc itself and jolt-build outputs) normalize to a .exe
suffix. workflow_dispatch added so the matrix can be dry-run without tagging;
the release upload step only fires on tags.

For #205.
