Crate cli_stream 

Generic streaming subprocess engine.

Spawn a child CLI, stream its stdout/stderr line-by-line through a callback as ProcessEvents, cancel it (SIGTERM → SIGKILL), and augment PATH so Node-based CLIs resolve even from a Finder-launched .app. No agent / harness protocol knowledge — it parses no CLI’s output and knows no agent’s wire format. The one node-specific concession is the best-effort PATH resolver (augmented_node_path): every consumer in this family drives a Node-based CLI, and as the shared leaf this is the one place bob-rs and agent-harness can both reuse it without a cycle. Otherwise it’s purely subprocess streaming, useful to anyone driving a CLI.

InstallEvent is the sibling shape for streamed install/login output.

This is a deliberate leaf crate: both bob-rs (the bob SDK) and agent-harness (the framework) depend on it, which is what lets bob-rs stay standalone without a dependency cycle.
