Publish @portableweb/cli v0.2.0 to npm

[omscse]

v0.2.0 is committed and pushed. Changes since v0.1.0:

• pweb pack now prompts for manifest details when manifest.json is missing in the source folder, rather than exiting with an error. Generates and writes manifest.json before packing.
• Shared prompt helpers extracted to src/prompts.ts (used by both init and pack).

Steps:

npm run build
npm publish --access public

Also bump portableweb (redirect package) after publishing so npm install -g portableweb pulls the new version.
