Implement authoritative ContextStatus state with typed descriptor delegation, immutable cancellation identity/origin metadata, and status-specific formatting. Retain the human’s _scope_tn rename. Correct transport-error classification and distinguish locally observed validation errors from boxed remote task failures.

The final working implementation passed 86 tests in 79.88 seconds using Trio0.34.0: sixteen new reason/status tests, sixty-five context stream semantics tests, and five IPC EOF regressions.
