DeployDiff v0.1.4

• Add a dedicated DeployDiff output channel with detailed command and remote operation logging.
• Add DeployDiff: Show Output Logs plus a Show Logs error action so users can jump straight to diagnostic output.
• Stop defaulting deploydiff.transport to mock; the transport must now be set explicitly to avoid accidental mock lookups.
• Improve missing-transport errors with an Open Settings action that jumps to deploydiff.transport.
