--worktree --tmux skips WorktreeCreate/WorktreeRemove hooks

Description

claude --worktree correctly fires WorktreeCreate hooks, but claude --worktree --tmux bypasses the hooks entirely and creates a git worktree directly at .claude/worktrees/<name>.

Steps to Reproduce

1. Register WorktreeCreate and WorktreeRemove hooks in .claude/settings.json
2. Run claude --worktree — hook fires, custom worktree creation works
3. Run claude --worktree --tmux — hook does NOT fire, git worktree created at .claude/worktrees/

Expected Behavior

--tmux should still fire WorktreeCreate/WorktreeRemove hooks, using the hook's stdout as the worktree path. The --tmux flag should only control how the session is displayed (in a tmux pane), not change the worktree creation mechanism.

Actual Behavior

--tmux uses a separate codepath that creates git worktrees directly, bypassing hooks. This breaks custom VCS backends (e.g., jujutsu workspaces) that rely on the hooks.

Environment

• Claude Code v2.1.81
• Linux (Pop!_OS)
• jj-colocated repo (has both .jj/ and .git/)

Workaround

Use --worktree without --tmux and manage the terminal pane separately.
