Add CI/release workflows and flatten package topology

Bundle the server with vite (single-file output, node-pty external) and
drop the npm workspaces layout in favor of one root package.json so the
release tarball is a flat runnable package — no workspace sub-packages,
no dev-dep bloat on install. A global install now gives consumers a
working web-shell bin.

CI runs typecheck + build on push/PR; release packs a tarball and
attaches it to a GitHub Release on v* tags.
