Docs & polish: DocC hosting, examples, SECURITY.md, localization

[JamesDale]

Summary

The documentation/polish bundle. Four of the five requested items are done; the fifth (relocating the README screenshots) needs the source image files, which this environment can't fetch — details below.

What's included

📖 Hosted DocC

• Enriched the catalog landing page, fixed the symbol links that broke when onError: was added to recognizeSounds/classifyActivity, and added a PrototypeKitError topic.
• New Docs workflow (.github/workflows/docs.yml) builds the DocC archive via xcodebuild docbuild, transforms it for static hosting, and deploys to GitHub Pages.
• One-time setup required: Settings → Pages → Build and deployment → Source → GitHub Actions. Then it serves at https://fridaytechnologies.github.io/PrototypeKit/documentation/prototypekit.

🧩 Sample app

• Examples/ gallery (PrototypeKitExamples.swift + README) demonstrating every feature — camera/Vision, Core ML, sound, motion, and Natural Language — including the new onError handler. It lives outside Sources/, so it's reference code the package never compiles; copy it into an app.

🔒 SECURITY.md

• Vulnerability-reporting policy pointing at GitHub private advisories.

🌐 Localization

• The two user-facing camera placeholder messages now go through NSLocalizedString with an en string table; set defaultLocalization: "en" in the manifest. Ready for additional .lproj translations.

Not done — needs your input

• README screenshots. The four setup images use rot-prone github.com/.../assets/… attachment URLs. Relocating them means committing the actual image files, but they return 403 through this environment's proxy, so I can't fetch them. If you drop the images into a repo folder (e.g. Documentation/Images/), I'll rewire the README to reference the committed copies.

Notes for reviewers

• Source-compatible; the only manifest changes are defaultLocalization and the existing resources.
• Authored without a local Swift toolchain, so CI here is the first machine build — the localization resource wiring (en.lproj + Bundle.module) and the docbuild step are the parts most worth watching.
