File hash renamer

Shinylive app that takes a batch of files, hashes each with SHA-256, and returns:

• a ZIP of the files renamed to <id>.<original-extension>
• filename-map.csv mapping new name → old name → full SHA-256
• ids.csv with the bare IDs, one per row

Runs entirely in the browser via WebAssembly — uploads never leave the client.

Develop

shiny::runApp("app")

Requires shiny, digest, and zip.

Deploy

Push to main → .github/workflows/deploy.yaml runs shinylive::export("app", "site") and publishes to GitHub Pages. Pull requests build but don't deploy.
