Fix duckAi selection by checking subdomains

Description

• Having setup a dev instance now, I noticed we're only supporting the bare domains in this list.
• I should make this list config driven but wiring that in here is a little annoying.

Note

Extend isDuckAi to recognize DuckDuckGo domains via subdomain-aware matching.

• Utilities (injected/src/utils.js):
  • isDuckAi: Replace exact hostname check with domains.some(domain => matchHostname(hostname, domain)) to support subdomains of duckduckgo.com, duck.ai, and duck.co.
