fix(ci): resolve 'codex-auth' in tsc via tsconfig paths; drop top README warning

CI failed because the demo imports the bare 'codex-auth' specifier, which only
the Vite alias resolved — plain `tsc --noEmit` (run before the build, so no
dist/) could not find it, cascading into implicit-any errors. Add a tsconfig
`paths` map (codex-auth + subpaths -> src/) so typecheck resolves the package
from source, independent of build order or symlinks.

Also remove the top-of-README research/education warning blockquote (the full
Disclaimer section at the bottom remains).

Verified the full CI sequence locally with dist/ removed: typecheck + build +
114 tests all green.
