book: Bitonic Sorter (Handwired series, book 11) - #158

Conversation
Batcher's bitonic sorter from the Wikipedia article (rev 1373262602), in four narrated chapters: the comparator and half-cleaner, building the mountains, the k(k+1)/2 staircase, and what a Handwired circuit pays for it, against ranks by counting (Handwired's own measurements). Placed after UI Exploration, whose loops guide measured the network; later books shift by one. Also paints the series background in ten Handwired lab chapters that left it to the host default (navy), and refreshes their previews. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Review comments at @docs/book-plans/handwired-bitonic-sorter/plan.md:
- Line 109: Update the two plan labels to match the shipped scenes: in the label
list near the bitonic sorter complexity description, replace “O(log^2 n) delay”
with “O(log^2 n) stages”; in the rank formula near the ranking description, add
the index tie-break condition so equal keys are ordered by j < i and explicitly
retain the ties-break-by-index wording.

Adds Bitonic Sorter, a four-chapter narrated book (9:20) on Batcher's bitonic sorter. It is based on the Wikipedia article, revision 1373262602.
It goes in the Handwired series as book 11, right after UI Exploration. That lab's loops guide measured a bitonic network against counting ranks, and a sorting network's fixed wiring is exactly what Handwired compiles. Books 11–16 move down one place.
