v1.2.0 — profile host-shadowing tripwire (--profile)
New check: flags a real-directory top-level @deepseek-ai/* copy in a dsh profile's node_modules that shadows the host instance and can break every tool call (discussion #1697).
- New CLI flag: dsh-plugin-doctor --profile ~/.dsh/profiles/web
- 10 unit tests (3 new), packaged plugin-shell smoke, full self-check all pass
- README EN/ZH updated
