v3.9.1

• dsh follow-ups that missed the 3.9.0 tag during a GitHub outage: the plugin row references the bare package name via a root export, so the dsh plugin list shows modlens instead of modlens/dsh; install lines use npx -y @deepseek-ai/dsh (the developer preview has no global binary); and both READMEs state the paste status honestly, since the dsh DeepSeek adapter declares text-only input and Web-UI image admission runs before any plugin hook, read_image is the working path today and paste auto-read stays wired for when images can enter.
