Convert launching preview commands to a single unified command

Background: In my project, I can provide sys.inputs.at("target") to control the target of a document. When a target is set to "webpage", it is compiled and suitable for viewing in website. When a target is set to "ebook", it is compiled as a e-book PDF and suitable for viewing in online or offline pdf viewer.

To edit styles for document targeting to "webpage", I want to launch preview with sys.inputs arguments.

Currently there are four commands to launch preview.

open
open in browser
open with slide mode
open in browser with slide mode

As feature increased (e.g. sys.inputs), the matrix becomes larger and unmaintainable. So I want to convert the "open/launch" action into a single command. And create four corresponding auto-detected tasks to replace these commands. The final effect should look like this:

We will have these auto detected tasks (also as a start-up task template):

open
open in browser
open with slide mode
open in browser with slide mode

And we can invoke a typst-preview.launch command in task:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "preview",
      "command": "${command:typst-preview.launch}",
      "args": {
        "openIn": "webview", // v.s. in browser
        "mode": "document", // v.s. slide mode
        "inputs": {
          "target": "webpage",
          "theme-setting": "themes/ayu.toml"
        }
      }
    }
  ]
}

All of arguments in typst-preview.launch are optional so we can also have a default command to launch without configuration or interactively.

And we can disable auto detected tasks as user preferences.
