Carlos Escalante bbae121fec Middleware audit for CK 1.62 / MAF 1.10: retire ReconcileSnapshot, inject dropped AG-UI context ...

- ReconcileSnapshotMiddleware removed: MAF now reuses the streamed
  message id in MESSAGES_SNAPSHOT (verified in _agent_run.py at
  python-1.10.0 and live event logs); keeping the surgery duplicated
  user messages on a2ui follow-up runs.
- beforeRequestMiddleware now injects RunAgentInput.context as a system
  message: MAF declares the field but never feeds it to the model,
  which starves the model of CopilotKit's A2UI catalog/guidelines.
  Remove when MAF consumes context upstream.
- Workaround chain env-gated: CK_MIDDLEWARES=off runs bare for audits,
  CK_DEBUG_EVENTS=1 enables the event logger.
- Kept: SuppressRenderToolText, StripModelArtifacts,
  DeduplicateToolCall, pairOrphanToolCalls (behavior-verified).
