Add iOS scaffold option

[Unknownamae]

Summary

• Adds ios to the bitbox new --scaffold option description.
• Maps --scaffold ios to https://github.com/Unknownamae/bitbox-scaffold-ios.git.
• The scaffold repo is a minimal native iOS WKWebView project that loads local web assets and displays Hello BITBOX with a generated 128-bit mnemonic using bitbox-cli/lib/bitbox-cli.
• The scaffold now includes the generated browser bundle and package lock, so the Xcode project can run immediately after cloning.

Fixes #13.

Small scaffold hardening update: the iOS scaffold repo now includes the generated Browserify bundle and package-lock, fixes the BITBOX import path to match the published npm package, and passes a full iOS simulator Debug build with xcodebuild. Commit: Unknownamae/bitbox-scaffold-ios@72b4283
