Context Object: State Management and Trace Propagation

apcore uses a shared Context object to carry trace IDs, call history, identity, and shared data across multi-step AI pipelines.

The design supports child contexts for nested calls, preserving trace propagation and execution history end to end.

This gives AI agents short-term shared memory plus better observability, making complex workflows easier to debug and control.

By tying context to ACL and trace standards like W3C TraceParent, apcore improves security, auditability, and governance.
