What
In the Experience Workspace Outline panel, a "Default content" run that holds a single item now starts expanded, so its one child is visible without a click. The run keeps its chevron and stays collapsible - only the default state changes. Multi-item runs are unchanged (still default-collapsed).
Closes #1306.
How
ew-page-outline.js: a run withchildren.length === 1rendersexpandedby default. Multi-item runs track open keys in_expandedContent; single-item runs default open and track explicit collapses in a symmetric_collapsedContentset. Both are keyed byproseIndex, both reset on a structural reparse._toggleContentGroup(key, single)flips the key in whichever set applies._expandRunForProseclears a single-item run's collapse so a doc selection always reveals it (the "selection never hides" invariant).Testing
test/unit/.../ew-page-outline.test.js: added cases for a single-item run showing its child by default with the chevron kept, collapse/re-expand on header click, and child selection. Existing tests that used single-item fixtures to assert default-collapsed behaviour were moved to multi-item runs.
