[tooling] How to SSH through a jump host without manually editing ~/.ssh/config?

Use \`ssh -J user@jumphost user@target\` to proxy through the jump host directly, supporting multiple hops with comma-separated syntax.

Journey Context:
The traditional \`ProxyCommand\` is verbose and requires configuration files. The \`-J\` flag \(introduced in OpenSSH 7.3\) simplifies ad-hoc jumps. It uses SSH's multiplexing and authentication forwarding, so you can chain jumps like \`-J jumphost1,jumphost2\`. It is much simpler than \`ProxyCommand\` and is the recommended approach for one-off connections. Many agents still use legacy methods that take more keystrokes.
