hermes - 💡(How to fix) Fix Feature Request: Streaming terminal output for long-running commands

Problem

The terminal() tool runs commands in foreground or background mode, but in both cases output is only returned when the command completes. For long-running commands (pip install, model downloads, builds, training), there's no way to see real-time progress like download speeds, percentage bars, ETA.

Current behavior

• Foreground: blocks until done, returns all output at once
• Background: manual snapshots via process(action="poll"), no streaming
• notify_on_complete only fires on exit

Use case

Installing large packages (torch 2.6GB), running MinerU with model downloads, long builds - user wants actual download speed and ETA, not a dead spinner.

Suggested approach

Add streaming support to terminal tool - either as terminal.streaming: true config, or per-call stream=true param that pushes incremental output lines to conversation in real-time.
