Release preparation 0.6

[SebastianSchildt]

I did some release pre according to https://github.com/eclipse-kuksa/kuksa-python-sdk/wiki/Release-Process

My intention was preparing for a minor 0.5.2 release, however I noticed the current setup did not work under Python 3.14 .

Fixing that required upgrading cmd2 package, which leads to a drop of Python 3.10 support (I decided to rather cut of 3.10 and raise minimum to 3.11 instead of not supporting 3.14, which already is default on some systems)

While doing that I also made sure the missing readline packages for Mac and Windows (that has been a long standing issue) are installed.

I also needed to update grpcio-tools (and protobuf) again, to make sure it does not need to compile (requiring a working C++ setup) due to unavailable wheels on current Python versions

Also the subscribe call in CLI was not working due to some issues in the val.v1/val.v2 switching code. If fixed that and checked against current 0.7 databroker as well as 0.4.6. (the last version with no v2 suppot whatsoever)

Due to this changes I would rather aim for 0.6 release...

So the plan is:

• Get this merged
• Push a 0.6-0-a1 pre-release
• test and iterate as often as possible
• Push 0.6.0 release
• ...
• Profit

(Note this is already a lot so I will except the markdown check failing due to know missing links tot he removed sdv1 protocol. I will remove those, when I am removing sdv1 support from the python package)

Pull request overview

Prepares the kuksa-client package for a 0.6 release by raising the minimum supported Python version, updating key dependencies for Python 3.14 compatibility, and fixing CLI gRPC subscription behavior across v1/v2 databroker APIs.

Changes:

• Raise minimum supported Python to 3.11 and update the release workflow accordingly.
• Upgrade cmd2/grpcio-tools/protobuf and regenerate pinned requirement files.
• Fix CLI gRPC subscribe handling to prefer v2 subscribe with a fallback to v1, and update CLI argument parsing/completion for cmd2 v4.
