Log Message:
fmtlib: update to 12.0.0.

# 12.0.0 - 2025-09-17

- Optimized the default floating point formatting
  (https://github.com/fmtlib/fmt/issues/3675,
  https://github.com/fmtlib/fmt/issues/4516). In particular, formatting a
  `double` with format string compilation into a stack allocated buffer is
  more than 60% faster in version 12.0 compared to 11.2 according to
  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark):

  ```
  Function  Time (ns)  Speedup
  fmt11        34.471    1.00x
  fmt12        21.000    1.64x
  ```

- Added `constexpr` support to `fmt::format`. For example:

  ```c++
  #include <fmt/compile.h>

  using namespace fmt::literals;
  std::string s = fmt::format(""_cf, 42);
  ```

  now works at compile time provided that `std::string` supports `constexpr`
  (https://github.com/fmtlib/fmt/issues/3403,
  https://github.com/fmtlib/fmt/pull/4456). Thanks @msvetkin.

- Added `FMT_STATIC_FORMAT` that allows formatting into a string of the exact
  required size at compile time.

  For example:

  ```c++
  #include <fmt/compile.h>

  constexpr auto s = FMT_STATIC_FORMAT("{}", 42);
  ```

  compiles to just

  ```s
  __ZL1s:
        .asciiz "42"
  ```

  It can be accessed as a C string with `s.c_str()` or as a string view with
  `s.str()`.

- Improved C++20 module support

- Switched to using estimated display width in precision. For example:

  ```c++
  fmt::print("|{:.4}|\n|1234|\n", "🐱🐱🐱");
  ```

  prints

  ![](https://github.com/user-attachments/assets/6c4446b3-13eb-43b9-b74a-b4543540ad6a)

  because `🐱` has an estimated width of 2

- Fix interaction between debug presentation, precision, and width for strings

- Implemented allocator propagation on `basic_memory_buffer` move

- Fixed an ambiguity between `std::reference_wrapper<T>` and `format_as`
  formatters

- Removed the following deprecated APIs:

  - `has_formatter`: use `is_formattable` instead,
  - `basic_format_args::parse_context_type`,
    `basic_format_args::formatter_type` and similar aliases in context types,
  - wide stream overload of `fmt::printf`,
  - wide stream overloads of `fmt::print` that take text styles,
  - `is_*char` traits,
  - `fmt::localtime`.

- Deprecated wide overloads of `fmt::fprintf` and `fmt::sprintf`.

- Improved diagnostics for the incorrect usage of `fmt::ptr`

- Made handling of ANSI escape sequences more efficient

- Fixed a buffer overflow on all emphasis flags set

- Fixed an integer overflow for precision close to the max `int` value.

- Fixed compatibility with WASI (https://github.com/fmtlib/fmt/issues/4496,

- Fixed `back_insert_iterator` detection, preventing a fallback on slower path
  that handles arbitrary iterators

- Fixed handling of invalid glibc `FILE` buffers

- Added `wchar_t` support to the `std::byte` formatter

- Changed component prefix from `fmt-` to `fmt_` for compatibility with
  NSIS/CPack on Windows, e.g. `fmt-doc` changed to `fmt_doc`

- Added the `FMT_CUSTOM_ASSERT_FAIL` macro to simplify providing a custom
  `fmt::assert_fail` implementation

- Switched to `FMT_THROW` on reporting format errors so that it can be
  overriden by users when exceptions are disabled

- Improved master project detection and disabled install targets when using
  {fmt} as a subproject by default

- Made various code improvements

- Added Conan instructions to the docs

- Removed Bazel files to avoid issues with downstream packaging

- Added more entries for generated files to `.gitignore`

- Fixed various warnings and compilation issues
