feat(workspace): migrate a2a-sdk from 0.3.x to 1.0.0 (KI-009) (#1974)
* feat(workspace): migrate a2a-sdk from 0.3.x to 1.0.0 (KI-009)

Migrates all workspace code from a2a-sdk v0.3.x to v1.0.0, following the
official migration guide from a2aproject/a2a-python.

Breaking changes applied:
- A2AStarletteApplication → Starlette route factory
  (create_agent_card_routes + create_jsonrpc_routes)
- AgentCard.url removed; url+protocol now in supported_protocols[].url
- AgentCapabilities fields renamed to snake_case
  (pushNotifications→push_notifications,
   stateTransitionHistory→state_transition_history)
- AgentCard.defaultInputModes/outputModes → default_input_modes/output_modes
- TaskState.canceled → TaskState.TASK_STATE_CANCELED
- a2a.utils → a2a.helpers
- Part(root=TextPart(text=t)) → Part(text=t) (TextPart removed)

Files changed:
- requirements.txt: pinned >=1.0.0,<2.0
- main.py: Starlette route factory + AgentCard restructure
- a2a_executor.py: Part() + TaskState + helpers import
- hermes_executor.py: TaskState + helpers import
- google-adk/adapter.py: TaskState + helpers import
- cli_executor.py: helpers import
- claude_sdk_executor.py: helpers import
- tests/conftest.py: a2a.helpers mock stub
- tests/test_a2a_executor.py: TaskState enum key
- adapters/google-adk/test_adapter.py: Part + helpers stub
