dsh-remote-ssh v0.2.1

dsh-remote-ssh v0.2.1 - one-command, zero-flag install

Installation is now:

1. git clone https://github.com/aijunjiang/dsh-remote-ssh && cd dsh-remote-ssh

ode scripts/install.mjs
3. restart dsh - start with no --patch

The installer links the monorepo packages into the profile loader tree AND
registers the SSH GUI user layer into the profile's own patch file (marked,
idempotent segment; removed with
ode scripts/install.mjs --remove).
README rewritten accordingly.
