feat: add clickable hyperlinks for URLs in terminal output

Use OSC 8 escape sequences to make tweet and list URLs clickable
in supported terminals (iTerm2, Ghostty, Kitty, WezTerm, VS Code, etc.).

- Add hyperlink() helper function in output.ts
- Apply hyperlinks in printTweets() for tweet URLs
- Apply hyperlinks in printLists() for list URLs
- Add hyperlinks flag to OutputConfig (auto-disabled for non-TTY)
- Automatically falls back to plain text in --plain mode or when piped
