fix(artifact): scanner type narrowing and url regex

- Use double assertion (`as unknown as Record<string, unknown>`) at lines 30
  and 90 to fix TS2352 per project convention
- Tighten URL_REGEX to avoid capturing trailing punctuation (parens,
  quotes, commas) when URL is embedded in text
- Add test case for array-form tool_result content path
