with full serialization roundtrip and test coverage.

Twitter long tweets (>280 chars) store full text in
note_tweet.note_tweet_results.result.text rather than legacy.full_text.
The parser now prioritizes note_tweet text when available.
Split the monolithic client.py (1341 lines) into three focused modules:
- graphql.py (~200 lines): queryId resolution, URL building, JS bundle
scanning, feature flag management
- parser.py (~270 lines): Tweet/User/Media/Article parsing, utility functions
(_deep_get, _parse_int, _extract_cursor, _extract_media)
- client.py (~700 lines): TwitterClient class with HTTP engine, anti-detection,
session management, and all public API methods
Backward compatibility: client.py re-exports all previously public symbols
so existing test imports work without modification. 88/88 tests pass.
