EnterWorktree resolves path to 'ready' instead of actual worktree directory

Bug

EnterWorktree fails with ENOENT on every invocation — it resolves the worktree path to the literal string "ready" instead of .claude/worktrees/<name>.

Version

Claude Code 2.1.114, macOS Darwin 25.4.0

Repro

EnterWorktree({ name: "any-name" })

Result:

Error: ENOENT: no such file or directory, chdir '/path/to/project' -> 'ready'

Expected: worktree created at .claude/worktrees/any-name and session chdir'd into it.

Evidence

• git worktree add via Bash works fine — git itself is not the problem
• No hooks, config, or project files reference the string "ready"
• ExitWorktree after the failed call confirms the internal path: "Exited and removed worktree at ready"
• The bug leaves the session in a half-entered worktree state (subsequent EnterWorktree calls return "Already in a worktree session")
• 100% reproducible, not intermittent

Workaround

Create worktrees via Bash directly, bypassing EnterWorktree.
