### Fixed

- Unexpected errors no longer occurred when the plug-in was unloaded.
- Hidden File Sync now respects selectors.
- Registering protocol-handlers now works safely without causing unexpected errors.

### Refactored
- LiveSyncManagers has now explicit dependencies.
- LiveSyncLocalDB is now responsible for LiveSyncManagers, not accepting the managers as dependencies.
    - This is to avoid circular dependencies and clarify the ownership of the managers.
- ChangeManager has been refactored. This had a potential issue, so something had been fixed, possibly.
- Some tests have been ported from Deno's test runner to Vitest to accumulate coverage.
