* fix(workspace): slide the content and header into place when a source opens
Opening an Xtream portal from the dashboard inserted the 323 px context
panel and the header Back in the frame that swaps the page: the content
pane jumped right by the panel's width and the switcher, search and actions
by Back's slot. That one frame was J2's whole layout shift (0.2327: 0.222
for the content pane, 0.011 for the header, scored with the pane's
distance), plus 0.0001 when the category search and sort buttons appeared
with the categories.
LayoutSlideDirective animates these moves as a 180 ms FLIP: the new layout
applies at once and only a transform animates, so nothing waits and no
layout shift is recorded. The content surface covers the strip it uncovers
while sliding, Back fades in, and reduced motion keeps the jump. The
category search and sort buttons render disabled while the list loads.
Locally J2 renderer.layoutShiftScore reads 0 (was 0.233), J1 0 / 0, J3
0.001, J4 0.

* perf(journeys): lower J2 layoutShiftScore to 0
The slides land on the runner: run 38147072417 (d2cb9445d) reads
open-source/renderer.layoutShiftScore 0 with no shift recorded in all 5
measured iterations (J1 0 / 0, J3 0.001, J4 0 unchanged). Ratchet the
baseline from 0.233 to 0 and record the perf:compositing evidence for the
slide in the shell contract.
