* Fix CI configuration broken by recent merges and tool updates
- gcc_flags.cmake: drop -Wexperimental-fmv-target, which GCC 16 accepts
only on aarch64; amd64 rejects it, so every GCC job failed while
checking the compiler.
- ci_get_cmake: add VERBATIM so the checksum pipeline is passed to the
shell intact (the unescaped `$'` broke the generated Makefile and
build.ninja, failing ci_cmake_flags and ci_module_cpp20); match the
SHA-256 entry case-insensitively, as CMake 3.5.0 lists the archive as
"Linux-x86_64"; and unpack with --strip-components, as that archive's
top-level directory is spelled "Linux" too.
- ci_single_binaries: compile json.hpp's TU without IWYU's --error, as
the comment above the gate already intends.
- tests: restore -Wno-deprecated-declarations for all non-MSVC compilers
(#5737 kept it for GCC only), as several tests call deprecated
functions on purpose; include thirdparty/fifo_map as SYSTEM.
- .clang-tidy: set misc-use-internal-linkage.AnalyzeTypes to false;
clang-tidy 22.1 extended the check to classes and enums and flagged
100 test helper types.

* Fix library warnings and a JSON_DIAGNOSTICS parent bug
- binary_reader: pass integers to sax->number_integer() through
conditional_static_cast<number_integer_t>, making the existing
narrowing for a narrow number_integer_t explicit (MSVC C4244 and GCC
-Wconversion/-Warith-conversion with the int16_t test from #5694);
mark two Infer DEAD_STORE false positives with @infer-ignore.
- to_json: set the parents of an array built from a C++20 range view
after all elements are in place; a reallocating push_back moved the
earlier elements and left their parent pointers stale, failing the
JSON_DIAGNOSTICS invariant assertion.
- json.hpp: suppress MSVC C4127 for the new is_ordered_map check in
diff(), like the three existing ones; spell out std::formatter::parse's
return and iterator types for clang-tidy 22.1.
- number_parse: make the Eisel-Lemire digit counter unsigned
(GCC -Wstrict-overflow).
- string_utils: take encode_utf8's callable by const reference
(cppcoreguidelines-missing-std-forward) and drop a \u from its doc
comment (-Wdocumentation-unknown-command).
- ordered_map: include <memory> for std::allocator (cpplint).
Ran make amalgamate.

* Fix tests failing in CI on develop
- unit-allocator: skip the #5640 test under MSVC STL iterator debugging,
where containers allocate a debug proxy in noexcept move constructors
and a failing allocation terminates; move a decrement out of an if
condition (bugprone-inc-dec-in-conditions).
- unit-conversions: expect the "(/0)" path with JSON_DIAGNOSTICS;
compare strict enums via get<>() rather than through the noexcept
operator==(ScalarType, json), which bugprone-exception-escape flags.
- unit-alt-string: suppress -Wexit-time-destructors for the strict enum
macro and misc-use-internal-linkage for its enum.
- unit-bjdata: call the static lookup functions through the type and
pass unsigned char (-Wsign-conversion on amd64).
- Mark Infer false positives with @infer-ignore in unit-diagnostics,
unit-pointer_access, unit-udt, and unit-conversions.
- Smaller clang-tidy 22.1 findings in unit-class_parser,
unit-constructor2, unit-custom-base-class, unit-locale-cpp, and
unit-noexcept.

* Enhance the UDT unit test to expose the issue
Add a new enum type with uint64_t as the underlying type.
Use it in the overall UDT. Not strictly needed, but it helps exercise its expected usage.
Create an object of this enum type with a large value (negative if cast to int64_t).
Perform several checks on this object as converted to `json`, which fail without the fix.
* Fix the issue in the relevant `to_json` overload.
Select the correct json type depending on the signedness of the enum's underlying type.
This fixes the new checks in the unit test.
* Add the fix to the single_include
I ran `make pretty` but that modified 20 files, performing a significant amount of indentation changes, none of them related to my change.
I ran `make amalgamate`, but that did nothing. Apparently, the make rule won't run if the single_include files have already been updated by `make pretty`.
I forced `make amalgamate` to do the work by touching the file with the fix.
I then decided to keep just the minimal needed change: the addition of the fix to the single_include file.
I just am not conversant enough in Linux to know whether I installed astyle correctly (had to clone the source from a beta branch and build, in order to get support for `--squeeze-lines`).
* Resolve CI errors and use qualified `std::uint64_t`
The fix was relying on implicit conversions in the non-taken branch.
- Ordinarily (work on a C++20 codebase) I would have used `if constexpr` here, sidestepping the issue, but that's not available on C++11 so I didn't bother.
- So instead of an `if` statement, I used a compile-time constant to select the correct overload.
- This is arguably better in this case, anyway.
I was using function-style casts for typed constants, which I consider superior for constants, but the CI checks disagree, so changed all to `static_cast`.
- For some reason, the CI checks didn't point at all of them, so I hope I caught them all myself.
Built with clang14 and all unit tests pass.
