Description

Brave's Dev Tools Console currently lacks a way to quickly search previously executed commands.

This is a feature developers may use in terminal environments like Bash, or the Node.js REPL via Ctrl+R reverse-i-search.

I think it'd be nice to have in Brave, as well.

Research direction
Investigate Chromium DevTools frontend code, specifically the console's command history component. Look for existing keyboard shortcut handling in the console area. The implementation would involve capturing Ctrl+R key event, implementing a reverse search UI overlay, and integrating with the command history data structure. Refer to the Terminal component's implementation in other Chromium sources for inspiration.
