Enhancement to emit a deprecation warning when the deprecated `snap_daemon` system username is used in snapcraft.yaml. Triaged by a maintainer; an open PR (#6250) explicitly fixes it and is pending review with CI failing.

Suggested action: keep open

Reason: The issue is triaged (labels 'Status: Triaged', 'Type: Enhancement') and is being actively addressed by open PR snapcraft#6250, which states it 'Fixes snapcraft#5448' and adds a SystemUsernames pydantic model plus a runtime warning via craft-cli. The repo's project.py still defines system_usernames as a plain dict with no deprecation model, confirming the fix is not yet merged, so the issue should remain open until the PR lands.

Issue body

### What needs to get done Snapcraft should add a deprecation notice if the `snap_daemon` system username is used. ```yaml system-usernames: snap_daemon: shared ``` ```bash Warning: The system username 'snap_daemon' is deprecated. See https://snapcraft.io/docs/system-usernames. ``` ### Why it needs to get done Because snapd has deprecated the username. See https://snapcraft.io/docs/system-usernames.
