In this commit we're cleaning up type issues in the core-data package that prevent us from telling TypeScript to run on the package and all of its existing code, even the JS files. After these changes we should be able to do so and start converting more modules to TypeScript with less friction. This patch follows a series of other smaller updates: - #39212 - #39214 - #39225 - #39476 - #39477 - #39479 - #39480 - #39525 - #39526 - #39655 - #39656 - #39659 It was built in order to support ongoing work to add types to the `getEntityRecord` family of functions in #39025.

Description
Part of #39211
Adds a nullity check and enhances a JSDoc comment to acknowledge
the nullable presence of a property in an object we test.
Testing Instructions
The only change here is a test for the presence of a
protocolvaluebefore accessing
.startWithon it. In production this has been a latentbug because that value may be undefined at runtime. In such a case the
editor will crash with a runtime type error.
Verify that the added safety guard is an appropriate way to handle this
potential failure, consistent with the approach for handling an invalid
protocol failure.
