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.
The Window Controls Overlay API applies a transparent overlay on
Windows, but not on Linux. This PR addresses this by capturing the area
underneath the overlay, averaging the color of the area, and setting
this as the overlay background color.
It will also detect whether to make the control symbols white or black,
depending on how dark the background color is.
On Linux, this will set both the background color and the symbol color,
on Windows it will just set the symbol color.

This makes it possible to send wsh commands from wsh on a remote session
to wavesrv running locally. The exact behavior of running those commands
isn't implemented, but the underlying interface is added here.
This PR implements the [Window Controls Overlay
API](https://web.dev/articles/window-controls-overlay) to let us hide
the menu bar on Windows and Linux and directly embed the window controls
in our tab bar. With #239 merged, we no longer need the menu bar on
these platforms.
The overlaid window controls are transparent so they will take on the
background from the app. I've updated the tab bar to flow properly using
the API's CSS environment variables.
At some point, we may want to update the logic around the symbolColor so
that it can ensure a proper contrast between the background and the
symbols in the window controls. For now, setting them to white works for
all the backgrounds we currently support.

This simplifies the rect calculations by making the gap between pixels
into a padding applied directly to the leaf nodes. This means the gaps
won't be present in the overlay layer, so when dragging a node around it
is always over an OverlayNode and the pendingAction won't be unset.
Also simplifies onDrop handling
