* Add iterator+sentinel tests and docs for binary deserializers
This commit extends the C++20 ranges support (iterator+sentinel pairs) to the
binary format deserializers from_cbor, from_msgpack, from_ubjson, from_bjdata,
and from_bson, matching what was already done for parse(), accept(), and
sax_parse().
Changes:
- Add istreambuf_sentinel helper to test_utils.hpp for EOF detection in tests
- Add 5 new test cases that read binary files directly via
std::istreambuf_iterator<char> + sentinel, without pre-buffering
- Update documentation for all 5 from_* functions to document overload (3)
with SentinelType parameter
- All tests pass; verified against existing test suite data
- Fix potential buffer over-read warning in heterogeneous iterator test

* Merge iterator+sentinel overloads and fix ambiguity/CI issues
Address PR review feedback and CI failures:
- Merge the separate same-type and sentinel-type iterator overloads of
parse(), accept(), sax_parse(), and the five from_* binary deserializers
into a single overload with SentinelType defaulted to IteratorType,
as suggested in review. Applied the same simplification to the
detail::input_adapter() free functions.
- Fix a latent ambiguity: some compilers (e.g. GCC 4.8) unreliably SFINAE
the operator!= detection for std::nullptr_t against container/string
types, making calls like parse(s, nullptr, ...) ambiguous with the
compatible-input overload. can_compare_ne now explicitly excludes
std::nullptr_t as a SentinelType.
- Use a named enable_if_t template parameter instead of an unnamed
function parameter for the SFINAE guard, fixing a clang-tidy
hicpp-named-parameter/readability-named-parameter failure.
- Update parse.md, accept.md, sax_parse.md, and the five from_*.md pages
to document the merged overload instead of separate (2)/(3) overloads,
also fixing an over-160-char line that broke the documentation
style_check CI job.
- Rework the BSON iterator+sentinel test to parse a BSON file already
present in the test suite instead of writing/deleting a temp file.

* Fix -Wunneeded-internal-declaration for CustomSentinel in test
CustomSentinel lives in an anonymous namespace (internal linkage), and
the library's parse loop only ever evaluates the iterator-first
direction (it != last), so the reversed-order friend operator!= was
never referenced. Clang's -Weverything flags such unused internal
declarations as an error. Drop the unused overload; the used direction
is enough to satisfy can_compare_ne's either-order detection.

* Fix clang-tidy hicpp-named-parameter and misc-const-correctness
- Drop the unused reversed-order operator!= overload from
utils::istreambuf_sentinel (only iterator != sentinel is ever
evaluated) and name the remaining friend's sentinel parameter, fixing
hicpp-named-parameter/readability-named-parameter.
- Mark the istreambuf_iterator first/last helper variable const in the
five binary-format sentinel tests, fixing misc-const-correctness.

* Fix clang-tidy misc-const-correctness in heterogeneous sentinel test
json_str is only read via .data()/.size() and never reassigned, so
clang-tidy correctly flags it as const-able. Verified against the exact
CI job (silkeh/clang:dev, ci_clang_tidy target) by running clang-tidy
directly on this file plus the five binary-format sentinel tests
touched by prior commits; all are now clean.
