Problem

Issues #103 and #104 are the easy even-layout new-pane cases: both layouts know the semantic tail up front, so explicit managed new-pane should not go through the generic append path first.

Solution

Closes #103. Closes #104 by making even-horizontal split the last pane with -h and even-vertical split the last pane directly, then adding direct fast-path tests for the dispatch semantics and the pre-relayout geometry.
