"Open with" doesn't work on Linux (at least)

[imm]

I built the app from source using PKGBUILD on Arch Linux.

The build was basically:

npm ci
npm run build
cargo build --release --locked --features tauri/custom-protocol

When I try to open any Markdown file using Scratch as the default app, the app's main screen opens instead of the file, as if it has absolutely no idea that it's supposed to open a file.

I also tried running it from the terminal

scratch-notes some-file.md

and got the same undesirable behaviour.

It's also disappointing to see that there are no CLI options at all. It's not even possible to check the version via the CLI.
