- Added SSH host management feature with `ssh` CLI command and `/ssh` slash command for add, list, and remove operations. - Added SSH configuration support at project (.omp/ssh.json) and user (~/.omp/agent/ssh.json) scopes with host discovery from project files. - Added SSH host configuration flags: --host, --user, --port, --key, --desc, --compat, and --scope for flexible host setup. - Removed automatic line relocation on stale hash references; now fails with error instead.
