feat: auto-wire the DSH plugin on install

The Windows installer no longer asks users to run dsh plugin add.
Post-install (and again when picking DeepSeek Harness) writes the
Cordis insert into the existing web profile, or a home-level patch
if DSH has not been initialized yet. Uninstall removes the wiring.
beautiCode still never starts DSH.
