  "message": "Optimize CommandLineV1Flag type dispatch, validation, and FlagSaver.\n\n1. Replace `IsOfType\u003cT\u003e()` (up to 6 virtual `TypeId()` calls + 6 indirect\n   `op_(kFastTypeId)` calls) in `ChangedDirectly`,\n   `CommandLineV1Flag::Typename()`, and `CommandLineV1Flag::InvokeValidator()`\n   with direct `op \u003d\u003d \u0026absl_flags::FlagOps\u003cT\u003e` pointer comparisons.\n2. Add `!inited_.load(std::memory_order_acquire)` fast paths to\n   `CommandLineV1Flag::ValidateDefaultValue()`, `IsModified()`,\n   `IsSpecifiedOnCommandLine()`, and `HasValidatorFn()`, avoiding lazily\n   allocating and locking ~8,000 `absl::Mutex`es during flag initialization.\n3. Return `nullptr` from `CommandLineV1Flag::SaveState()` when unmodified and\n   restore via `CommandLineV1Flag::RestoreToInitialState()`, eliminating\n   ~8,000 `Clone(op_, cur_)` + `V1FlagState` heap allocations/deletions per\n   `FlagSaver` scope.\n\nPiperOrigin-RevId: 989386175\n",
