[Bug] EnterWorktree fails when agent has cwd override in isolated mode

Bug Description
When using claude agents --cwd ., some times (like in this session) the agent is unable to edit files, and all the attempts error out. It starts when it tries to create a worktree and gets the error:

⏺ Creating worktree(issue-553-admin-logout-redirect)
⎿  Error: EnterWorktree cannot be called from a subagent with a cwd override (isolation:
"worktree" or explicit cwd) — it would mutate the parent session's process-wide working
directory. This agent is already isolated in its own working copy.
