Gate the prompt command behind a prompt feature

Discussed in #2155

How can I exclude crate rfd from the qsv build? Crate rfd breaks my qsv build on a headless server that has no window manager because it indirectly requires crate wayland-sys which fails to build because wayland-sys cannot find wayland-client which isn't installed.

Thank you for implementing the prompt feature. Did you intend for all_features to include prompt? all_features in Cargo.toml includes prompt, but FEATURES specifies that all_features does not include prompt. Is it possible to instruct cargo build to exclude a feature that a feature list includes?

[derekmahar]

Note that I now successfully build qsv using the command

cargo build --release --locked --features "feature_capable apply fetch foreach geocode lens luau polars python to"

Would it be useful to group these features in a feature list named console_features, for example?

Glad to know you can build qsv now on your headless server.

As for prompt not being documented in FEATURES.md, that was an oversight on my part and have since updated it.

As for creating a console_features grouping feature, let's bookmark that for now until we get more commands that require a window manager. Right now, prompt is the only one - though technically, you can actually still build and run it headless by just installing libwayland-dev like we do on the publishing workflows.

qsv/.github/workflows/publish.yml

Lines 153 to 156 in 7c76af7

	- name: apt-get update Ubuntu, libwayland-dev
	run: |
	sudo apt-get update
	sudo apt-get install libwayland-dev

All commands requiring a GUI, going forward, will be on qsv pro.
