Description of Change

Removes a handful of avoidable per-call costs from gin_helper paths that run on every native event emit, IPC message, option-dictionary parse, and C++ → JS callback.

• EmitEvent / CallMethodWithArgs — internalize the event name and "emit" (gin::StringToSymbol); reuse the emitter as the node::CallbackScope resource instead of allocating a throwaway v8::Object; drop the redundant inner EscapableHandleScope.
• gin_helper::Dictionary — internalize property keys; replace Has() + Get() in Get() with a single GetRealNamedProperty() (one V8 boundary crossing instead of two), guarded by a zero-cost HasNamedLookupInterceptor() flag check that routes native-interceptor objects (process.env, etc.) to the original path.
• gin_helper::Locker — store v8::Locker inline in std::optional instead of heap-allocating per construction.
• Converter<char16_t>::FromV8 — read the UTF-16 code unit directly instead of round-tripping through UTF-8.
