Calling :cmd:title:`<cmd>` will generate a cross reference to `<cmd>`, but unlike :cmd:ref: which displays a literal block and puts the title (short_help) in the hovertext (the title field of an a-ref), :cmd:title: will display "<cmd> - <short_help>" as plain text.
Thus replacing the previous use case of referring to :doc:`cmd/<cmd>`.
Also refactor util py scripts to have more descriptive names.
Changes a bunch of :doc:`/cmd/*` to :cmd:ref:`*` with the intention of changing it later to something that replicates the previous effect of displaying the commands `short_help`.
Moved remaining content into relevant places.
Added `load_design.rst` to more scripting.
Split fsm handling and abc out of optimization passes. Also moved things around to match the general flow previously described.
Changed generic `synth` for `prep` instead.
