pub fn run_create() -> Result<()>Expand description
Handle a Claude Code WorktreeCreate hook event.
Claude Code’s payload carries worktree_name (and cwd/base_commit) but
NOT a worktree path — the hook itself is responsible for creating the
worktree and reporting where it landed. We read the payload from stdin,
delegate to gw new --emit json --term skip (self-reexec), parse the
resulting JSON, and print only the created worktree_path as a plain-text
line to stdout — exactly what Claude Code’s hook contract expects.
Human-readable progress output from the inner gw new call flows through
to stderr unchanged, so the user can see what’s happening.
