Add Allrecipes adapter

[ankitranjan7]

Summary

• add browser-backed Allrecipes recipe extraction adapter
• command added:
  • webcmd allrecipes recipe <url>
• extract recipe JSON-LD/visible page data from recipe URLs
• normalize HTML entities in returned text
• keep recipe rows within webcmd row-shape limits by returning 12 top-level fields
• regenerate cli-manifest.json

Verification

• webcmd doctor
• npm run build-manifest
• npm run typecheck
• npm run check:silent-column-drop
• npm run check:typed-error-lint
• npm test -- clis/allrecipes/allrecipes.test.js
• npm test
• live verified:
  • node dist/src/main.js allrecipes recipe https://www.allrecipes.com/recipe/23600/worlds-best-lasagna/ --format json
• webcmd browser verify --strict-memory allrecipes/recipe passed with a tightened local fixture

Notes

• Direct server fetch to Allrecipes can hit Cloudflare/browser verification, so this adapter uses browser-backed extraction through the webcmd/Cloak flow.
