Convert div elements to anchor tags in FileTree and HeadingNode to
enable native browser features like middle-click to open in new tabs.
The implementation preserves SPA navigation for left-clicks while
ensuring search parameters are preserved in the href.
Switch from fixed positioning to a flexbox-based layout for the
main application structure. This introduces a `ScrollContainerCtx` to
provide access to the main scrollable element, allowing child
components like `FileTree` and `RevealManager` to perform accurate
scrolling and positioning relative to the container instead of the
window.
refactor: set JournalPanel height to full
Introduce `useNavigateWithParams` to ensure that existing URL search
parameters are maintained when navigating between pages. This is
applied to the Article component, FileTree, and journal links to
prevent losing state (like session or player info) during client-side
navigation.
Also intercepts markdown anchor links in the Article component to use
client-side navigation.
Add support for hiding file tree nodes and headings based on path
revelation status. This allows the sidebar to dynamically show only
the relevant parts of the file structure and table of contents.
