fix(windows): shrink the pull-away reveal to the minimum window height

minimize-window floors at window-min-height (4 lines), leaving roughly a 10% reveal. Bind window-min-height to 1 around it so the reveal opens at the ~2-line floor and the current window keeps almost the whole frame before the windsize arrows take over.

 Reported by .emacs.d 2026-06-12 01:01: the dedicated pager number (+15045173983, the Claude Pager Google Voice number on signal-cli) returns "User ... is not registered" on every send — Signal appears to have deregistered it (GV numbers get periodically re-verified). Re-registration requires captcha/SMS, which only you can do. Until then every page-signal call fails; .emacs.d's config-audit page fell back to email.

 ** 2026-06-20 Sat @ 10:29:42 -0400 C-; b + arrow pulls a window away from a sole window
-Decided with Craig 2026-06-20: when the selected window is the sole window, =C-; b= + arrow keeps that window on the arrow's edge and slivers =other-buffer= in on the opposite side (=minimize-window=, so the current window keeps almost the whole frame), focus staying put; each further arrow then shrinks it step by step via =windsize=, reading the same as resizing an existing split. Generalizes to any sole window, not just terminals — resize was a no-op there before. Built in =modules/ui-navigation.el= (=cj/window-pull-side= pure mapping + =cj/window--pull-away= + a =one-window-p= branch in =cj/window-resize-sticky=). ERT tests for the mapping and both sticky paths; geometry verified in a headless frame (down -> terminal 35/40 at the bottom, reveal slivered on top, windsize-down then steps it 35->33->31); full suite green; live-reloaded into the daemon. Refined from a first cut that split toward the arrow and jumped to 50%, per Craig's feedback. Manual gesture check filed under Manual testing and validation.
