Detailed Description

RenderSessionRepl is the stdin/stdout-driven command loop that sits on top of RenderSession. It exists so that render-session tooling can be driven (and tested) without an ImGui window - the shell layer is a thin parser that maps line-based text commands to RenderSession methods and writes human-readable output.

The REPL is parameterized by std::istream& + std::ostream& instead of hard-coding std::cin/std::cout, so headless tests can feed a scripted input stream and assert against the captured output without touching the real terminal.

Supported commands (one per line, whitespace-separated):

help - list commands load <uri> - fetch + render reload - re-fetch the current URI resize <w> <h> - re-render at a new viewport status - print the latest status line show - render the current frame to the terminal (ANSI) save <out.png> - write the current bitmap as a PNG watch on|off - toggle filesystem mtime polling for auto-reload quit / exit - leave the loop
