Mohamed BoudraandGitHub 2298e9efdf Fix composer toolbar collapse flicker on tab switch (#2937)
Retained tabs stay mounted under display:none while inactive, which
reports a zero-width onLayout. ControlledAgentControls fed that
straight into its density resolver, so a hidden tab's toolbar
collapsed to its tightest density and painted one frame collapsed
before re-expanding when the tab became visible again.

Extract the zero-width guard that useContainerWidthBelow already had
into a shared readMeasuredWidth helper, and use it in the composer
toolbar's own layout handler so a display:none measurement can never
drive its density.

Also bump the chat outline rail's MIN_PANEL_WIDTH breakpoint (818 ->
918) so the rail disappears earlier under a narrower panel, and widen
the chat-outline e2e spec's viewport so its panel keeps healthy margin
over the new threshold.
