Fix issue with CMake 4.0

Soon CMake 4.0 will be released. It requires that projects
set a minimum required CMake version of 3.5. There is a
workaround with an additional flag, but it would is better
to increase the minimum required version.

Bump the release note to the latest version

Including iostream means introducing the static (global) constructors
and destructors for std::cin, std::cerr, and std::cout. That extra
init and fini code is undesirable when those streams are not actually
used.

Instead, we'll use the narrower includes for exactly what's needed,
i.e., <istream> or <ostream>.

Accept Emitter::operator<<(std::string_view).

ABI remains C++11 compatible by exposing new method
Emitter::Write(const char*, size_t).

All affected calls optimized to pass std::string values as pointer + size
tuple into appropriate routines.

Add some details about testing.

Including:
- Remove WORKSPACE and upgrade to MODULE.bazel.
- The integration tests were not included since the directory was misspelled.
- Their header files were not accessible.

Goole Test itself documents the `INSTALL_GTEST` option as something that projects embedding it should set to `OFF`. Leaving it on means that projects downstream from libraries that embed it are likely to encounter conflicting copies. This is particularly annoying because GTest does not maintain anything like a stable API, and so causes builds to fail if include paths pick up an inappropriately installed copy ahead of the one that the code wanted.

Fixes #488

Add dragonbox to compute the required precision to print floating point
numbers. This avoids uglification of floating point numbers that
happen by default via std::stringstream.

Numbers like 34.34 used to be converted to '34.340000000000003' as strings.
With this version they will be converted to the string '34.34'.

They were commented out before 0733aeb4, but when that commit
was reverted in 2b65c65e they were recovered uncommented.

Amends 26faac38.

GCC 15 will no longer include it by default, resulting in build
failures in projects that do not explicitly include it.

Error:

this is probably fixable by adding '#include <cstdint>'

Tests pass.

jekyll/liquid got hung up on `{{"Daniel", 26}, {"Jesse", 24}}`.

The reason is that `{{...}}` are used as variables that are replaced by
there values. In this case we have a YAML object that looks the same.
This issue can be fixed by surrounding the block into `{% raw %}...{%
endraw %}` tags.

This reverts commit 1f5e971f.

See #1306; the previous commit caused an error with -Wpedantic:

yaml-cpp/include/yaml-cpp/emitterstyle.h:13:2: error: extra ‘;’ [-Wpedantic]

Since the original commit was to resolve warnings, reverting and the OP can produce a new one that fixes this issue.
