The `psl` crate's domain_str / suffix_str do byte-exact lookups against the public-suffix list, so uppercase or trailing-dot inputs (e.g. "Example.COM" or "example.com." from a DNS Name) silently return None. Several call sites were passing through user- or DNS-supplied domains unmodified. Add a small psl-utils crate that wraps the psl crate: * normalize_domain(&str) -> Cow<str>: strips a single trailing dot and lowercases ASCII; borrows when the input is already normalized so the hot path (alignment loop) doesn't allocate. * domain_str / suffix_str: thin re-exports for callers that have already normalized. psl-utils becomes the only workspace crate that directly depends on the psl crate; kumo-dmarc and mod-string switch to depending on psl-utils instead. Updated call sites: * kumo-dmarc record.rs: is_relaxed_aligned / is_strict_aligned now normalize both inputs first. Replaces the prior eq_ignore_ascii_case comparisons. * kumo-dmarc lib.rs: the organizational-domain fallback in DmarcContext::check now normalizes from_domain before calling domain_str and compares against the normalized form. Previously a mixed-case From: header would skip the _dmarc.<org> lookup entirely. * mod-string lib.rs: the Lua-exposed string.psl_domain and string.psl_suffix bindings normalize their input. Behavior change: inputs that previously returned nil due to case or trailing dot now resolve. Co-authored-by: Wez Furlong <wez@wezfurlong.org> Closes: https://github.com/KumoCorp/kumomta/pull/513
