[Bug] EnterWorktree tool ignores WorktreeCreate/WorktreeRemove hooks

Bug Description
EnterWorktree tool does not invoke WorktreeCreate/WorktreeRemove hooks

When WorktreeCreate and WorktreeRemove hooks are configured in .claude/settings.json, the claude --worktree CLI flag correctly invokes them. However, the in-session EnterWorktree tool (used when asking Claude to switch to a worktree mid-conversation, or via Agent(isolation: "worktree")) ignores these hooks entirely and uses built-in git worktree add instead.

This means any repo that needs custom worktree setup (e.g. git-crypt key symlinking, sparse checkout, post-checkout dependency installation) works with --worktree but fails mid-session.

Repro:

1. Configure a WorktreeCreate hook in .claude/settings.json
2. Start Claude normally (without --worktree)
3. Ask Claude to switch to a worktree – EnterWorktree runs built-in git worktree add, hook is never called

Expected: EnterWorktree should invoke WorktreeCreate/WorktreeRemove hooks the same way the --worktree CLI flag does.
