Pull request #7: Update Electron
Author: login: l3laze
Created: 2025-04-08T20:49:56Z | Merged: 2025-04-15T15:15:24Z

* Bump Electron from v16 to v35.
* Add `package-lock.json` for best reproducibility.
* Add `nodeIntegration: false` to `webPreferences`, as Node is not needed in the app.
* Replace `path` in `preload.js` with a `path.basename` polyfill and add `webUtils.getPathForFile` as `ipc_bridge.path_for_file`.
* Update `renderer.js` to use `ipc_bridge.path_for_file` to replace the removed Electron-only `file.path`.

body: Good catch. Was thinking about how Windows supports `/`, but didn't consider that the path from Windows could still use `\`. Late nights strike again.

Updated to use `path.sep`. Can attempt to squash back into one commit, but I think that will invalidate this PR and require closing it and opening another.

body: No problem :) It came up in a [question on Arqade](https://gaming.stackexchange.com/questions/411569/how-to-get-rpg-maker-mz-save-files-out-of-indexed-db) (on the Stack Exchange network with Stack Overflow), and I noticed it was a bit outdated when I tested it.

I also spent about a day trying to convert it to a modern web app, but didn't understand the file format well enough based on your code. It can load the save data and import the RMMZ-provided lzstring or Pako scripts though, which seems like enough to remove the need for Electron. Still early draft, but I dropped it [in a gist](https://gist.github.com/l3laze/09abae62b9232ad4b5ffa1df50631c30) if you're interested.
