Build System Migration

[skjsjhb]

The build system of Alicorn has been working well, but also being bloated and hard to maintain.

We're deploying a progressive migration from webpack to a faster and neat toolchain based on esbuild + vite. This requires frontend (i.e. renderer) to be rewritten, moving all Node calls to the backend.

This refactor is also expected to drastically improve the security and performance of Alicorn, most noteworthy the usage of isolated context will further prevent RCE and delegate jobs to be scheduled more suitably.

This issue should remain open until the migration is done.
