v5.10.8

• Asking an AI to install modsearch inside DeepSeek Harness (dsh) now installs the dsh plugin (#42). INSTALL.md used to install the skill everywhere, but dsh already has its own web_search tool, so the skill was never called and searches kept going to dsh's default provider. INSTALL.md now starts with a dsh step: when DSH_SHELL=1 is set, it installs the plugin into the running profile (DSH_PROFILE, so the desktop app's desktop profile is covered too), checks it with --dump-config, and skips the skill. The README says the same next to the install sentence, and the skill tells a model inside dsh to point the user to the plugin.
