fix(install): add early systemd detection to prevent mid-install failures

Browse Source 
- Enhance `handle_systemd()` to check for `/run/systemd/system` and exit early if systemd is not PID 1, with user-friendly error messages.
- Update README.md notes for Devuan and SYSTEMD_MODE to reflect the new behavior and clarify requirements.

- NOTE: The Debian project is no longer using a standard package name for `libasound2`. Not to worry, apt will automatically select the `libasound2t64` packages it needs. For all derivative distributions, therefore, the package name will remain "libasound2".

- NOTE: server-mode installation is unavailable here, because Devuan does not use systemd. The installer detects this and refuses `SYSTEMD_MODE=install` up front rather than failing mid-install.

- `NOTSUPPORTED=1` — Skip dependency checks entirely (install them yourself)
