chore(vscode): use unjs/unbuild for bundling

[KermanX]

Use https://github.com/unjs/unbuild to bundle the VSCode extension, also as a preparation for #4994.

Notes:

• To dev the extension: run pnpm dev:vue, the command will exit after the stub files generated (no need to watch file changes), then F5. (Should the tasks defined in .vscode/tasks.json and .vscode/launch.json be restored?)
• To build the extension: like before.
• Other packages except the VSCode extension remain unchanged.

Hey, what do you think about switching to tsdown, powered by Rolldown, for faster speed?

[filipsobol]

I noticed that you've replaced sonda with rollup-plugin-visualizer. I will not try to convince you to use sonda, but if this was a technical decision, could you share the reason? I would appreciate your feedback so I can improve it.

Hi @filipsobol, first of all thank you for developing sonda. One of the reasons is that we want the PR to keep the most relevant changes so that it has a greater chance of being merged. Another reason is that the output file treemap is paginated in Sonda, and we cannot visually check whether the modules that need to be shared by multiple files have been correctly split.

Thank you, this gives me some interesting ideas 🤔

Another reason is that the output file treemap is paginated in Sonda, and we cannot visually check whether the modules that need to be shared by multiple files have been correctly split.

By visual check, do you mean manual or automated visual check? You should be able to switch between chunks using the dropdown menu in the upper-left corner, but I can imagine that it may require extra work or even problems in automated tests (e.g. if it visually compares two reports).
