Now, Self-hosted LiveSync has finally begun to be split into the Self-hosted LiveSync plugin for Obsidian, and a properly abstracted version of it.
This may not offer much benefit to Obsidian plugin users, or might even cause a slight inconvenience, but I believe it will certainly help improve testability and make the ecosystem better.
However, I do not see the point in putting something with little benefit into beta, so I am handling this on the alpha branch. I would actually preferred to create an R&D branch, but I was not keen on the ampersand, and I feel it will eventually become a proper beta anyway.

### Refactored

- Separated `ObsidianLiveSyncPlugin` into `ObsidianLiveSyncPlugin` and `LiveSyncBaseCore`.
- Now `LiveSyncCore` indicates the type specified version of `LiveSyncBaseCore`.
- Referencing `plugin.xxx` has been rewritten to referencing the corresponding service or `core.xxx`.

### Internal API changes

- Storage Access APIs are now yielding Promises. This is to allow more limited storage platforms to be supported.

### R&D

- Browser-version of Self-hosted LiveSync is now in development. This is not intended for public use now, but I will eventually make it available for testing.
- We can see the code in `src/apps/webapp` for the browser version.
