CLI worktree: node modules not copied over to the worktree folder

[rebornix]

Does this issue occur when all extensions are disabled?: Yes/No

Re #277163

The current behavior is likely by design as creating a new git worktree will not copy node_modules over. However it becomes a problem the moment I browse the files in the current workspace. TypeScript language server will read the file and complain that there are missing packages.

A couple of ideas:

• do we want to support copying node_modules or similar packages dependencies when creating new git worktree?
• do we want to make it extensible that users can configure post script for git worktree?
• should the language servers/extensions ignore git worktree? (which is then a step down as I still wish to use some language features)

do we want to make it extensible that users can configure post script for git worktree?

I would opt for this.

Sorry for jumping in but I think this is a really good approach, cursor did something similar that works really well:
