## Message

```
Avoid fork PR head branch collisions when creating worktrees

- create a unique local branch name for cross-repo PR worktrees (`pr/<number>-<head>`)
- fetch/set upstream against that local branch instead of overwriting local `main`
- add regression tests for fork PRs where head branch is `main`

```
