Collapse the netty worktree helpers into wt create/remove/prune, keep wt-create as a thin wrapper, and drop the standalone wt-path command.
Also make the netty zsh wrappers handle cd-only behavior for wtc and wt remove.

Resolve the path anchor from the repository common git dir so running wtc from inside an existing worktree still names sibling worktrees from the main checkout root.

Add netty-specific worktree helper commands and a zsh wrapper that creates sibling worktrees and cds into them.
Also split script packaging so Darwin keeps the existing wt integration while netty gets git-worktree-based helpers.
