v1.5.0

pdd show/hide could only address a pet by the folder it was bound to, which made a --no-cwd pet unreachable — no folder resolves to it, and hatching never opens its window on its own. They now take a pet id the same way delete and update already do, with --cwd still available to name a folder instead. This also fixes the Orca worktree hook in the CLI README, which was already calling pdd show --cwd, a flag that didn't exist yet.
