Build me a self hosted web app for organizing a private media collection, especially adult videos and images but it should also work for normal personal media. I want to point it at folders on my computer or server, have it scan everything, make thumbnails and previews, and let me browse the collection in a clean web interface.

It should let me tag items, edit names and descriptions, group things by performer, studio, tags, and folders, and search or filter easily so I can find stuff later. I also want useful stats about the library, like counts by tag, performer, studio, and media type.

Add a setup flow for first run where I choose media folders and basic settings. If possible, include support for pulling metadata from online sources and community scrapers, with a plugin style system so more sites can be added later. Make it run locally in a browser, and include simple install or Docker instructions. Look up current docs online if you need to.
