Walkthrough

The initData function in the tree-menu renderless module now returns early when props.lazy is truthy, bypassing the existing logic that populates state.data from props.data or fetches menu data via service.getMenuDataSync() followed by api.setMenuKey(...).

Changes

Lazy Tree-Menu Initialization

Layer / File(s)	Summary
Early return for lazy loading packages/renderless/src/tree-menu/index.ts	initData now checks props.lazy and returns immediately, skipping the props.data assignment and service.getMenuDataSync()/api.setMenuKey fetch logic.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Poem

A hop, a skip, a lazy switch,
No fetch, no key, no data glitch. 🐇
When lazy's true, I pause and wait,
Short-circuit joy, a tidy fate!
