With this PR, Electron will generate a new authorization key that the Go
backend will look for in any incoming requests. The Electron backend
will inject this header with all requests to the backend to ensure no
additional work is required on the frontend.
This also adds a `fetchutil` abstraction that will use the Electron
`net` module when calls are made from the Electron backend to the Go
backend. When using the `node:fetch` module, Electron can't inject
headers to requests. The Electron `net` module is also faster than the
Node module.
This also breaks out platform functions in emain into their own file so
other emain modules can import them.
This PR is a large refactoring of the layout code to move as much of the
layout state logic as possible into a unified model class, with atoms
and derived atoms to notify the display logic of changes. It also fixes
some latent bugs in the node resize code, significantly speeds up
response times for resizing and dragging, and sets us up to fully
replace the React-DnD library in the future.
This PR swaps usage of the `uuid` library for the built-in
`crypto.randomUUID` function, which is available in both NodeJS and the
browser. The built-in function is around 12x faster than the `uuid`
library. The strings produced by the built-in function are fully
compatible with the UUIDv4 standard, so it's an easy switch.
