fix(server): prefer origin/{branch} over local branch for worktrees

When creating a worktree, resolve the base branch by checking origin/{branch} first, falling back to the local branch only when the remote ref doesn't exist. This ensures worktrees start from the latest upstream state rather than a potentially stale local branch.
