Switch to worktree

Switch the current session to an existing worktree.

Steps

1. Resolve the worktree

If $ARGUMENTS is empty, list available worktrees and ask the user to pick one:

git worktree list

Otherwise, let NAME = $ARGUMENTS. The worktree path is <repo-root>/.worktrees/<NAME>.

Verify the worktree exists in git worktree list output. If not, stop with an error.

Let WORKTREE = the absolute path to the worktree.

2. Switch cwd

cd WORKTREE

Then verify the switch took effect:

pwd

If pwd does not show WORKTREE, stop with an error — the cwd did not persist.

3. Report

Switched to worktree: WORKTREE
Branch: <current branch from git branch --show-current>
