+Add SSH isolation support for remote command execution.
+
+- Implements SSH backend for executing commands on remote servers via SSH, similar to screen/tmux/docker isolation
+- Uses `--endpoint` option to specify SSH target (e.g., `--endpoint user@remote.server`)
+- Supports both attached (interactive) and detached (background) modes
+- Includes comprehensive SSH integration tests in CI with a local SSH server

+ *
+ * These tests require a running SSH server accessible at localhost.
+ * In CI, this is set up by the GitHub Actions workflow.
+ * Locally, these tests will be skipped if SSH to localhost is not available.
+ *
+ * To run locally:
+ * 1. Ensure SSH server is running
+ * 2. Set up passwordless SSH to localhost (ssh-keygen, ssh-copy-id localhost)
+ * 3. Run: bun test test/ssh-integration.test.js
