Doc: add 5 SVG logo concepts and a light/dark preview page

Five concepts in doc/ — kanban board, sprint arrow, sprint cycle,
planner calendar, SP monogram. Primary strokes use currentColor and
each standalone .svg includes a svg:root + prefers-color-scheme block
so it adapts to OS theme when used as a favicon, in a README, etc.
doc/logo.html inlines them via <symbol>/<use> and renders each mark
side-by-side on a light and a dark panel so the two themes can be
compared directly.

The primary strokes use <code>currentColor</code> so they invert with the surrounding theme; the indigo and emerald accents are picked to hold contrast on both backgrounds. The standalone <code>.svg</code> files include a <code>svg:root</code> + <code>prefers-color-scheme</code> block so they also adapt when used as a favicon, in a README, or otherwise displayed on their own.</p>
