[Bug]: ran into error code “0x80010135” when unzip the code on Windows 11

### What happened?

A bug happened!

I downloaded the code zip (instead of git clone), and when I unzip the code, an error happened

The windows error code is: 0x80010135
And it seems the length of this file's path is way too long: MultiInstanceReplicationApp1AgentExecutorProducer.java

I did some searching. It turns out that the longgest path length in windows is 260 characters. The full path of this file is:

"a2a-java\extras\queue-manager-replicated\tests-multi-instance\quarkus-app-1\src\main\java\io\a2a\extras\queuemanager\replicated\tests\multiinstance\app1\MultiInstanceReplicationApp1AgentExecutorProducer.java"

**The length of this string is as high as 207, which is very close to the system upper limit.**

An easy solution is enable windows' long path support:
1. Win + R: regedit
2. find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
3. create LongPathsEnabled DWORD (32-bit)
4. set the value to 1
5. reboot the system

### Relevant log output
