feat: support rich content in long-form tweets (X Articles)
Add support for extracting rich content from X's long-form tweets, including embedded code snippets, markdown blocks, quoted tweets, and other structured content that was previously lost. Changes: - Add fieldToggles with withArticleRichContentState to TweetDetail API request - Implement Draft.js content_state parser (renderContentState) that converts blocks and entities to readable markdown format - Add content_state type definition to GraphqlTweetResult Supported content: - Block types: paragraphs, headers, ordered/unordered lists, blockquotes - Entity types: MARKDOWN (code blocks), DIVIDER, TWEET, LINK, IMAGE No impact on regular tweets - rich content only adds payload when present. Includes 20 unit tests for the parser and an opt-in live smoke test. Co-authored-by: Christian Catalan <[email protected]>
