cendor-sdk 1.1.1

Fixed

• Agent(max_usd=…) is now enforced on a single-agent run(), not only in orchestrated/
  multi-agent runs. The per-agent USD cap was previously applied only inside the orchestrator's
  per-segment scope, so a plain run(agent, …) billed with no ceiling. The single-agent run and
  stream paths (sync + async) now wrap the same pre-flight budget(on_exceed="block") scope the
  orchestrator uses, so an over-budget call is refused before it is sent — identical semantics to a
  multi-agent segment.
• Resuming an already-completed checkpoint no longer re-runs the model or its tools. Resuming a
  run whose checkpoint is marked done now short-circuits and returns the stored result
  (steps == [], zero model calls, zero tool calls) instead of rebuilding from the original input and
  replaying the whole loop. Applies to single- and multi-agent runs, sync and async.
