Use the same command for getnameverison in both firmware and apps

[dehanj]

To ensure that other client apps can get what app is running, and present an adequate error to the user,the getnameversion command needs to be the same regardless of device-app or firmware.

In firmware we have defined it as:
FW_CMD_NAME_VERSION (0x01)
FW_RSP_NAME_VERSION (0x02)

The protocol of the signer and all apps using it should be change to the above.

Hm, feels like you had the chance to do this for the 1.0 release, but now it feels harder.

For my tkey-device-x25519 I used the same 0x01 and 0x02 like fw does, but alas...

You are right.
For 1.0 release we chose not to make breaking changes to the protocol to ease migration, i.e., you can use either version of the signer with either version of tkey-ssh-agent if you just load the app with tkey-runapp for example.

But in the long run it might be better to move to something else, like proto buffer or something.
