This commit upgrades TypeScript to the latest version 5.3 and introduces
`verbatimModuleSyntax` in line with the official Vue guide
recommendatinos (vuejs/docs#2592).
By enforcing `import type` for type-only imports, this commit improves
code clarity and supports tooling optimization, ensuring imports are
only bundled when necessary for runtime.
Changes:
- Bump TypeScript to 5.3.3 across the project.
- Adjust import statements to utilize `import type` where applicable,
promoting cleaner and more efficient code.
The tree view rendering performance is optimized by improving the node
render queue ordering. The node rendering order is modified based on the
expansion state and the depth in the hierarchy, leading to faster
rendering of visible nodes. This optimization is applied when the tree
nodes are not expanded to improve the rendering speed.
This new ordering ensures that nodes are rendered more efficiently,
prioritizing nodes that are collapsed and are at a higher level in the
hierarchy.
