change AUR URL schema from HTTPS to SSH

Error message

change AUR URL schema from HTTPS to SSH

What it means

Same HTTPS-to-SSH URL rewrite as in config.rs, performed on the config during run2 before constructing the fetch backend. The expect panics when replacen(...).parse::<Url>() fails, i.e. the configured aur_url is not a parseable https URL. It is an invariant failure caused by an invalid user configuration.

Solutions

1. Correct aur_url in paru.conf to a full https:// URL such as https://aur.archlinux.org/.
2. Drop any ssh://aur@ prefix from aur_url; paru applies it automatically when Ssh = true.
3. Set Ssh = false if you want to keep a non-https URL untouched.

Example fix

// before
AurUrl = aur.archlinux.org
// after
AurUrl = https://aur.archlinux.org/

grep -E '^AurUrl' ~/.config/paru/paru.conf  # must be full https:// URL

fn is_https_url(s: &str) -> bool { s.starts_with("https://") && url::Url::parse(s).is_ok() }

When it happens

Trigger: Running any paru command that reaches run2 with Ssh enabled and an aur_url that is empty, scheme-less, already ssh://, or otherwise not a valid https URL.

Common situations: Hand-edited paru.conf with AurUrl set to an ssh URL or a bare hostname; environment where config file was migrated from another AUR helper with a different URL format.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
