Bug: generating ID for agent removes digits as well

[mivanick]

Expected Behaviour

if an agent name includes digits e.g. 'Image2You' a generated agent id should be 'image-2-you' or 'image2you'

Current Behaviour

currently the regex in 'generate_key_from_name' method in 'agents.py' https://github.com/awslabs/multi-agent-orchestrator/blob/main/python/src/multi_agent_orchestrator/agents/agent.py#L52 removes digits as well leaving agent id without digits

agent name 'Image2You' becomes image-text

this can result in incorrect identification of agents because you can have e.g. 'image2you' and 'image4you' agents and they would become image-you and image-you hence orchestrator would say that agent with the same id already exists

Code snippet

agent = BedrockLLMAgent(BedrockLLMAgentOptions(
    name='Image2You',
    description='Some description'
))

orchestrator.add_agent(agent)

all_agents = orchestrator.get_all_agents()

for agent_id, details in all_agents.items():
	agent_name = details['name']
	print(f"Agent ID: {agent_id}, Agent Name: {agent_name}")

Possible Solution

change regex pattern to '[^a-zA-Z0-9\s-]' to include digits in generated agent id

Steps to Reproduce

agent1 = BedrockLLMAgent(BedrockLLMAgentOptions(
name='Image2You',
description='Some description'
))

agent2 = BedrockLLMAgent(BedrockLLMAgentOptions(
name='Image4You',
description='Some description'
))

orchestrator.add_agent(agent1)
orchestrator.add_agent(agent2)
