Installing dependencies in new worktrees

[Chudesnov]

Whenever I create a new branch / worktree, there are some initial steps before I start working there.

Specifically, without running npm / pnpm / yarn in the worktree root, some of the VSCode plugins are not working properly:

• ESLint
• prettier
• typescript
• Jest

because these rely on node_modules which aren't copied automatically (and in most cases shouldn't be, since their versions could be different). What if GitLens+ had a setting to run such prerequesite commands for each new worktree?

I'm wondering if this is a separate issue from having VSCode workspaces pre-configured for new worktrees (#1956), or those could be solved by the same set of features.
