fix: remote ide no longer reconnects after plugin upgrade (#167)

When the plugin is upgraded while JBClient is connected to a remote dev server via the Coder SSH proxy/tunnel, the upgrade process kills and re-establishes the SSH connection. However, JBClient/Toolbox fails to detect the restored connection and reports "Toolbox: Target environment com.coder.toolbox:bobiverse-bob.dev not found" error. While digging into the Toolbox bytecode—specifically `ClientOverSshTunnelConnector` — I realized the issue likely stems from an incorrect equals implementation in our custom SSH connection info object. In short, when a plugin upgrade terminates the SSH tunnel, the connector’s monitoring logic correctly detects the lost connection and waits. But when the SSH connection is re-established, the monitoring logic fails to recognize it as a valid replacement, because equals is still using the default `Object#equals` rather than a proper value-based implementation. Unfortunately, I wasn’t able to properly test this—specifically, upgrading from a version without the fix to one that includes it—because all Toolbox marketplace feeds are signed, preventing us from using a tool like mitmproxy to serve a locally modified plugin version. Given that, I propose releasing the change first and then performing the upgrade test to confirm the fix. - resolves#61
