/**
 * Shared qualified-name normalization.
 *
 * One canonical transform from a raw, language-specific qualified name
 * (`Other::Inner`, `pkg\Sub\Type`, `  A . B `) to the `.`-joined form the
 * graph and the `QualifiedNameIndex` are keyed by (`Other.Inner`, `pkg.Sub.Type`,
 * `A.B`). Extracted from `class-extractors/generic.ts` so the structure-phase
 * `buildQualifiedName`, the scope-resolution inheritance resolver, and the
 * per-language capture emitters all key against ONE normalizer — a raw `::`
 * qualifier must normalize to the exact key the index already holds, or the
 * qualified lookup silently misses (issue #1982).
 *
 * Do NOT confuse with `heritage-extractors/supertype-alternation.ts`'s
 * `simplifyRawName`, which collapses a qualified name to its LAST segment
 * (`Other::Inner` → `Inner`) — that is a tail extractor, not a normalizer, and
 * using it as a lookup key guarantees a miss.
 *
 * Pure string functions; no AST or tree-sitter dependency.
