ExAthena.Terminal.Server (ExAthena v0.17.0)

One GenServer per embedded web terminal.

Owns an interactive shell via erlexec (a real pseudo-terminal: prompt, colors, job control, Ctrl-C), streams its output to the owning LiveView as themed HTML, and dies with its owner (shared-fate cleanup). Output is coalesced on a short timer so a flood (yes, a big cat) becomes a few LiveView diffs instead of thousands of messages.

Started on demand under ExAthena.Terminal.Supervisor, named by terminal id in ExAthena.Terminal.Registry (mirrors Orchestrator.Coordinator).

This is a COMMAND-RUNNER terminal — line-streaming with SGR colors. The output renderer (ExAthena.Terminal.Sgr) does not emulate cursor control, so full-screen TUIs (vim/htop) are out of scope by design.
