docs: add headless parse checks and correct the rofi version

The plan claimed rofi 1.7.3, taken from a stale comment header in the user's
config.rasi. The installed version is 2.0.0.

Adds a `-dump-theme` parse check to the palette and each layout task. This
catches syntax errors without a display, which the plan previously treated as
impossible and deferred entirely to visual inspection. Every theme file in the
plan was verified to parse cleanly on 2.0.0.

Replaces the palette verification step, which built a throwaway wrapper theme
via printf just to have something that draws. A palette defines variables and
renders nothing, so there was nothing to look at; parsing is the real check.
