Doc improvement: Clarify version alignment for Git-cloned clients

[eternamaze]

Hi,

I ran into a "silent" failure because I compiled the client from the latest Git source but used a stable pre-compiled Windows Host binary.

Even though the docs advise against building from source for beginners, many still do. It would be very helpful to add a specific reminder: "Git source is always the bleeding-edge version. Ensure version parity between Host and Client."

Adding this would save a lot of troubleshooting time for new users. Thanks!

There is technically a check, but if I recall correctly it broke because the message header was re-arranged to better fit cache lines on bleeding edge at some point (can't find the commit right now). Since then the detection doesn't get far enough to warn about mismatched versions but just fails earlier

Yes, this is on my task list of things to address, it should be showing a warning but it's a low priority issue to address
