Pull request overview
Adds a new JIT design document that captures the proposed semantics for general runtime-async inlining. The doc is meant to guide future implementation work by spelling out how suspension, resumption, context flow, and exception handling would need to behave when async callees are inlined.
Changes:
- Introduces a new design note for preserving
ExecutionContextand continuation-context behavior across inlined runtime-async calls. - Describes a proposed
resumed_*model and post-inline IR needed to reconstruct logical async returns. - Adds worked examples covering synchronization-context and
AsyncLocalbehavior.

I expect to work on general inlining for runtime async over the next few weeks. This document writes down my thoughts around what needs to happen in the inlined code.
Mostly this is low level details for my own sake, but still cc @agocke @AndyAyersMS @VSadov @stephentoub.
