  "message": "Optimize `AlphaNum` and `substitute_internal::Arg` for compile-time constant integers and `bool`.\n\nPassing `bool` or compile-time integer literals to `StrCat`, `StrAppend`, `Substitute`, or `SubstituteAndAppend` previously promoted `bool` to `int` and invoked out-of-line `FastIntToBuffer` at every call site. For small or bounded constants, each call site allocated scratch buffer space, set up arguments, and called `FastIntToBuffer` at runtime even when the formatted ASCII digits were statically known at compile time.\n\nAdd a constrained `AlphaNum(T b)` constructor template matching `bool` directly (indexing `\"01\"` in one `lea` instruction while keeping non-`char*` pointers rejected at compile time) alongside a `SingleArgStrCat(bool)` fast path. Introduce shared C++17 `inline constexpr` lookup tables and `strings_internal::FormatIntToPiece` across all integer `AlphaNum` and `substitute_internal::Arg` constructors so constants in `[-9, 99]` reference static `.rodata` slices without touching scratch storage and constants in `[-999, 9999]` constant-fold into immediate byte stores without calling `FastIntToBuffer`.\n\nPiperOrigin-RevId: 1003917448\n",
