Keep track of the storage ID in each renderer Storage instance and pass
it to the IPC bridge. Jobs are dispatched to the relevant handler (only
saves/ for now) and all (de)compression is handled there.
Add dedicated fs-job types to read or write and (de)compress data
from/to the file picked by the user. Remove redundant utility functions
that used web APIs instead.
* Migrate Electron wrapper to ESM
Use ESM syntax for main process, move some fs usages to fs.promises,
switch to import.meta.url/import.meta.dirname to handle file paths;
clean up redundant code.
* Add TypeScript support to Electron wrapper
The support is very basic, tsc is used to transpile code. Build scripts
are modified to not copy any Electron code other than preload.cjs and
use an extremely cursed setup to call the TypeScript compiler.
* [TS] Rename platform/storage
* Rewrite Electron wrapper
MVP, missing some features from the old wrapper and most planned
features. Some of the functionality hasn't been verified.
