Contradictory definitions of the `just dev` command in README.md

[gitishman]

There is a contradiction in the README.md file regarding what the just dev command actually does.

1. In the "Quick start" section (around line 171), it says that just dev starts both the relay and the desktop app:
   just dev # starts the relay + desktop app together

2. Right below it (around line 176), in the instructions for a split-terminal workflow, it says to use just desktop-dev for the desktop app:
   For a split-terminal workflow (relay logs separate from Vite output), use just relay in one terminal and just desktop-dev in another.

3. However, later in the "Common dev commands" section (around line 262), just dev is listed as running only the desktop app, which contradicts point 1:
   just dev # Run the desktop app
