API pages should show related links from composable/component counterparts #152
Description
Problem
The dedicated API pages (/api/:name) don't display any related links. The composable and component pages define related in their frontmatter (e.g., createSlider links to Slider and vice versa), but the API page for either has no connection to its counterpart.
Expected
API pages should surface the related links from the corresponding composable or component page, so users can navigate between:
/api/createSlider→/composables/forms/create-slider/api/createSlider→/components/forms/slider/api/Slider→/composables/forms/create-slider
Context
Discovered while reviewing the createSlider API page — no way to navigate to the composable docs or the Slider component from the API reference.
