fix(deploy): use lines[-1] for wrapper CID + add version to summary (#86)

PR #85 took lines[-2] from the IPFS gateway response, copying
aleph-cloud-app's pattern. But their tree shape differs: they prefix
paths with `out/` so lines[-2] gives them the served root inside an
extra wrapper. Our flat paths produce one wrapper at lines[-1] and
random sub-directories at earlier indices — the last deploy was
serving from a sub-directory, so HTML loaded but nested asset paths
(/_next/static/...) 404'd, breaking all styling.

Also adds CURRENT_VERSION (extracted from src/changelog.ts in the
workflow) to the deploy summary so the deployed version is visible
without inspecting the build.
