e2: Output ESM instead of CJS for main and preload scripts

[jermy-c]

• update better-sqlite3 to 11.2.1 since older versions don't work with electron@32
• update electron-vite to 2.3.0 to support ESM
• update electron to 32.0.1 to support ESM
• use custom ESM shim plugin since the one in electron-vite doesn't seem to work nor the @rollup/esm-shim plugin, therefore causing the __dirname syntax error
• fix syntax errors to be compatible with ESM
• set the config to output ESM for main and preload scripts
• in the main script set the preload to mjs because it outputs it with themjs file extension for some reason

Where should we point the esm-shim-plugin package? It is a package based on rollup/plugins#1709 (comment). Will it be moved to Mustang?

Good changes. Thanks a lot for figuring that out!
I'm glad that it's not as difficult as I thought to change compliation to ESM.

If it works well (please test carefully!), and if you can avoid the shim, then it's good to go. The remaining changes look good to me, assuming that everything works.

You're welcome. Thanks!

• I replaced esm-shim with @rollup/plugin-replace, now it replaces all instances of __dirname with import.meta.dirname for the output. But it requires Node v20.11.0 or later. Would that be better or do we still do the shim()? NOTE: It is only a release candidate for now and not stable feature yet. https://nodejs.org/api/esm.html#importmetadirname
• Removed unnecessary config for ESM electron-vite config
• It is normal for the preload script file extension to change to .mjs or .cjs when outputing ESM. https://electron-vite.org/guide/dev#enabling-esm
• I tested the build i.e.yarn build:mac and it works.

Great! Thank you. Much simpler = better. There's a `__dirname` in our src/main/index.ts . Would it make sense to replace that? Do we still need the replacement in this case? I assume yes, and that's OK.

[jermy-c]

Yes, but it'll replaced by the replace plugin also. So, we don't need to replace it manually.

[benbucksch]

Could you please replace it?

[jermy-c]

Could you please replace it?

Ok, done.
