kagent run silently fails if name contains unsupported characters (e.g. `-`)

[peterj]

1. kagent init adk python hello-agent
2. kagent run .

Run command hangs because of this error:

ValidationError: 1 validation error for LlmAgent
hello-agent-1  | name
hello-agent-1  |   Value error, Found invalid agent name: `hello-agent_agent`. Agent name must be
hello-agent-1  | a valid identifier. It should start with a letter (a-z, A-Z) or an underscore 
hello-agent-1  | (_), and can only contain letters, digits (0-9), and underscores. 

We shoul fail in the init command if the name contains unsupported characters

@peterj is it correct?

• when i used command ./kagent-dev init adk python my-agent

• but when used kagent init adk python hello-agent it gives

is it because the binary is generated locally?
