Summary:
Move sync workers and Edgehill token checks to work window
Move the task queue and database setup to the work window
Move ContactStore background refresh to work window
Store the task queue in the database
WIP
The TaskQueue now puts tasks in the database instead of in a file, which also means it can be observed
Move all delta sync and initial sync to a package, make NylasSyncStore which exposes read-only sync state
DraftStore no longer reads task status. Once you set the "sending" bit on a draft, it never gets unset. But that's fine actually.
If your package lists windowTypes, you *only* get loaded in those windowTypes. If you specify no windowTypes, you get loaded in the root window.
This means that onboarding, worker-ui, worker-sync, etc. no longer get loaded into the main window
ActivitySidebar has a special little store that observes the task queue since it's no longer in the window
Move "toggle component regions" / "toggle react remote" to the Developer menu
Move sync worker specs, update draft store specs to not rely on TaskQueue at all
Test Plan: Run existing tests, all pass
