* refactor(domain): consolidate canonical ordering and digest helpers Single owner for code-point ordering (domain/canonicalOrdering.ts) and canonical JSON digests (domain/comparisonSemantics.ts). Delete all local compareCodePoints/compareText/digestCanonical duplicates and migrate every importer. No re-export shims. * fix(ci): allow slower real browser startup
