alliscode baff7e33e1 feat(workflows): support combined message + checkpoint_id for multi-turn continuation ...

Allow Workflow.run(message=..., checkpoint_id=...) so callers can restore
prior workflow state from a checkpoint AND deliver a new message to the
start executor in a single call. The existing reset_context logic
already preserves shared state when checkpoint_id is set, so this gives
us 'fresh start executor invocation with prior state intact' - exactly
what hosted multi-turn declarative workflows need.

- _workflow.py: drop the message+checkpoint_id mutual exclusion and
  update _execute_with_message_or_checkpoint to do both (restore then
  execute) when both are provided.
- _agent.py: in _run_core's checkpoint branch, also forward
  input_messages so WorkflowAgent.run(messages, checkpoint_id=...) works
  end-to-end. Falls back to the legacy 'restore only' behavior when
  messages are absent.
- _declarative_base.py: detect continuation in _ensure_state_initialized
  by checking whether DECLARATIVE_STATE_KEY already exists in shared
  state; if so, refresh inputs/LastMessage* and append non-user trigger
  messages instead of calling state.initialize() (which would wipe
  Conversation/Local/System).
- foundry_hosting/_responses.py: collapse the host's two-call pattern
  (restore-only, then fresh run) into a single combined call now that
  the underlying APIs support it.
- tests: drop the assertion that combined message+checkpoint_id raises.
