Some sites return 403/FORBIDDEN to the default Defuddle UA. Allow users to override it with --user-agent / -u. When set, the bot-UA fallback retry is skipped to respect the explicit choice. Co-Authored-By: Claude Opus 4.7 (1M context) <[email protected]>

Summary
--user-agent/-uflag todefuddle parseso users can override theUser-Agentsent when fetching a URL. The default UA (Mozilla/5.0 (compatible; Defuddle/1.0; +https://defuddle.md)) gets 403/FORBIDDEN from a number of sites; this gives an easy escape hatch without touching the library.Example:
npx defuddle parse https://example.com/article \ --user-agent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.0 Safari/605.1.15"The plumbing was already there —
fetchPage(targetUrl, userAgent, language?)insrc/fetch.tsalready takes a UA — this just surfaces it through the CLI.Test plan
npm run buildsucceedsnode dist/cli.js parse <url> --user-agent "<ua>"uses the supplied UA (verifiable with a request bin /httpbin.org/user-agent)node dist/cli.js parse <url>without the flag still uses the default UA (existing behavior unchanged)--helpshows the new option🤖 Generated with Claude Code
