Add worktree_setup configuration for bootstrapping new worktrees

[conorbranagan]

Overview

Adds the ability to bootstrap a worktree with commands + copy over files that are explicitly ignored. This is useful for getting your worktree into a working state for claude to be able to test things locally.

Might do better as a per-repo config, but wanted to keep the changes limited to the existing config. You can workaround this, as shown in the example, to only run commands when specific files exist.

Changes

• Added worktree_setup config section with:
  • copy_ignored: List of glob patterns for gitignored files to copy
  • run: List of commands to execute after worktree creation
• Validates and skips absolute paths (starting with /)
• Only copies files that are actually gitignored

Example config

{
  "worktree_setup": {
    "copy_ignored": [".env.local", "config/*.secret"], 
    "run": ["[ -f package.json ] && pnpm install || exit 0", "cp .env.example .env"]
  }
}

@conorbranagan I just came across this, looks like it's possible to add a hook that runs after creating a worktree: https://mskelton.dev/bytes/using-git-hooks-when-creating-worktrees

might be more better than handling it inside of cs, since it's a standard git feature

Ah, I had looked for this originally but guess I missed it. Agreed that going the hooks route is a better approach, thanks for the pointer. I'll close this one out.
