Add post: Why Chrome Forgets Its Tabs in a Container (EN + ZH)

- docker/Chrome/CDP gotcha: the container kills the browser, so it never exits
  cleanly and no restore mechanism fires (flag, Preferences, managed policy all
  verified failing) -> 60s snapshot + replay keeper
- also covers the stale Singleton* lock and custom-cont-init.d permission traps
- custom OG + banner art, EN + ZH, backlog B2 updated
