The ZIP installer now contains a `libs/bin` folder that contains
`ifcmerge`. Bonsai on `register()` adds this folder to the system `PATH`
for the current Blender session. Advantage of this is that we don't have
to fiddle with the registry on windows, or install files to
`~/.local/bin` on Linux, it _should_ work on Darwin, updates are
automatic, and we have a mechanism to ship other executables if
required.
(Note that ifcmerge.exe increases the size of the Windows Bonsai ZIP
download by about 7MB)
If Git isn't installed on Windows, the Git panel now offers to install
it from the Windows Package Manager Community Repository using `winget`.
Apparently (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62572) coreutils have changed `mv -n` to throw an error now instead of working silently, therefore our build was failing on Mac when Github Action switched from Ubuntu 22 to 24.
`--update=none` seems to restore the old behaviour.
Recently released Python 3.12.6 dropped support for Mac OS 10.9-10.12 - https://www.python.org/downloads/release/python-3126/
And Python 3.12.6 is the one that's used by compiled builds from now - in our case it was fonttools (used by ezdxf) that compiled binaries and it's using cibuildwheel which is also started using Python 3.12.6 as it's released.
