Rob Lourens e6e776a4b6 Add SSH remote agent host bootstrap (#304882)
* Add SSH remote agent host bootstrap

Adds a new ISSHRemoteAgentHostService that automates connecting to a
remote machine via SSH, installing the VS Code CLI, starting
'code agent-host', and forwarding the agent host port back through
the SSH tunnel.

- New service interface and types in common/sshRemoteAgentHost.ts
- Full implementation using ssh2 in electron-browser/ with dynamic
  imports to respect layering rules
- Multi-step quick input flow for SSH connection details integrated
  into the remote agent host picker
- 'Connect via SSH' command registered in contributions

* Address PR review feedback

- Strip password/privateKeyPath from ISSHAgentHostConnection.config
  so secrets are not exposed to consumers after connect
- Redact connection tokens (?tkn=...) in all log output and error
  messages to prevent credential leakage
- Parse user@host:port format in SSH host input with proper validation
  for port range and missing components
- Guard onDidClose with a closed flag to prevent double-fire when
  dispose and SSH close/error events overlap
