[FEATURE] Add tags to tools to use them downstream in the A2A AgentCard Skill

[juliangrueber]

Problem Statement

I would like to add tags to tools, so they can be populated in the AgentCard when hosting an A2A server

Proposed Solution

No response

Use Case

Publishing an agent card with skills that include tags

Alternatives Solutions

No response

Additional Context

A2A Skill definition: https://a2a-protocol.org/latest/tutorials/python/3-agent-skills-and-card/#agent-skills

Strands A2A implementation where tags is always an empty list since the type tool does not have that property:

sdk-python/src/strands/multiagent/a2a/server.py

Lines 160 to 163 in 8e6f48a

	return [
	AgentSkill(name=config["name"], id=config["name"], description=config["description"], tags=[])
	for config in self.strands_agent.tool_registry.get_all_tools_config().values()
	]
