Improve wording of China digital nomads article per style guide
Apply systematic corrections: replace "on" with "je" when the author
speaks, remove intensifiers (très très, absolument, ultra), fix informal
register (galères → difficultés, dingue → déconcertante, lagger → ramer),
remove anglicisms (digitaux → numériques, startup → entrepreneuriale,
app → application, budget → économiques), fix grammar errors (mandiants,
sans de dépendances), split long sentences, add HappyCow link, and add
one reader challenge after the GFW conclusion.
