inflictx/Arsenal ? reverse-engineered prompt

Build me a local, offline first web app for pentesting and bug bounty work that runs on my machine and keeps everything in a local database or in the browser, with no account or cloud stuff.

I want one fast searchable place for payloads, GTFOBins, wordlists, reverse shells, Burp notes, checklists, and engagement notes. It should have a click to build command generator where I can pick a tool, toggle flags, and copy the finished command. Add an embedded CyberChef area for quick encoding and decoding, a reverse shell generator, a tracker for targets and findings, and markdown report export. It would also be great to have Russian and English switching, favorites, backups, and a global search that finds anything across the app.

Please make it polished, quick to use, and useful for real authorized security testing. If you need to look up current docs or examples online, go ahead.
