/**
 * C++ inline namespace support (U5 of plan 2026-05-13-001).
 *
 * `inline namespace v1 { void foo(); }` has two ISO C++ semantics that
 * GitNexus must model:
 *
 *   1. **Transitive unqualified visibility.** Names declared in an inline
 *      namespace are reachable by unqualified lookup from the enclosing
 *      namespace's scope, as if they were declared directly there.
 *      `populateCppNonGloballyVisible` (file-local-linkage.ts) treats
 *      inline-namespace members as globally visible for cross-file
 *      unqualified lookup.
 *
 *   2. **Transitive qualified visibility.** `outer::foo()` resolves to
 *      `outer::v1::foo()` when `v1` is inline. The qualified-namespace
 *      receiver resolver (`resolveCppQualifiedNamespaceMember`) walks
 *      inline-namespace children transitively when collecting candidates.
 *
 * State lifecycle: capture-time `markCppInlineNamespaceRange` records each
 * inline namespace's source range; `populateCppInlineNamespaceScopes`
 * resolves ranges to `ScopeId`s during `populateOwners`. Cleared via
 * `clearCppInlineNamespaces`, called from `clearFileLocalNames`.
 *
 * STL idiom this enables: `std::__1::vector` (libc++) and `std::__cxx11`
 * (libstdc++) are inline namespaces of `std`. With this support,
 * `std::vector` qualified calls resolve to the inline-namespace
 * declaration transparently.
