c9f7264d - Continue evolving `Context` towards a data structure that can be sent over the wire (#788)

Continue evolving `Context` towards a data structure that can be sent over the wire (#788) * `Args` doesn't need to hang off of `Context` * `TraceFilePath` isn't used, tracing is done via `RunState` instead. * global hash calculations and root `package.json` calculations can use local variables * `TaskGraph` is unused.
