Niels Lohmann ad2c14b985 Document response times, supported versions, access, secrets, and dependency policies (#5580)
Answer the OpenSSF Best Practices criteria that asked for policies the
project follows but had not written down:

- SECURITY.md: a first response within 14 days, publishing an advisory
  with credit once a fix is released, and that only the latest release
  receives security fixes.
- Governance: who has access to the project's resources, how write or
  admin access is granted, and how CI secrets are stored and rotated.
- Quality assurance: how dependencies of the build, test, and
  documentation tooling are pinned, scanned, and kept free of known
  vulnerabilities.

Also update the assurance case, since comparison no longer recurses per
nesting level (#5390), and point the best practices badge and links to
bestpractices.dev under the program's current name.

Niels Lohmann e94e164b07 Add BON8 support
Add to_bon8/from_bon8 and input_format_t::bon8 for BON8, a binary format
that uses the byte values that cannot begin a UTF-8 character as type
markers, so strings need no length prefix. It is the most compact of the
supported binary formats on the benchmark files.

The reader is non-recursive like the other binary readers. A string ends
at the first byte that cannot continue it, so the reader hands the one or
two bytes it reads past a string back to the value that follows. The
writer produces the canonical representation of the specification, except
for NFC normalization; its output is identical to that of the reference
implementation (HikoGUI) on all files of the test data.

The round-trip tests need the .bon8 files of json_test_data 3.2.0.

Niels Lohmann 85889e8843 docs: use HTTPS for the astyle and cppcheck links in README (#5351)
* docs: use HTTPS for the astyle and cppcheck links in README

Both links were still `http://`. `astyle.sourceforge.net` serves HTTPS
directly; `cppcheck.sourceforge.net` redirects to
`https://cppcheck.sourceforge.io`, which is also the URL already used in
`docs/mkdocs/docs/community/quality_assurance.md`, so the redirect is
skipped here.

* CI: suppress -Wc2y-extensions for Clang

Clang 22.1 (now shipped by silkeh/clang:latest) diagnoses __COUNTER__ as a
C2y extension, and does so in C++ mode as well. Under -Weverything -Werror
this breaks every ci_test_clang_cxx* / ci_test_clang_libcxx_cxx* target,
independently of the code under test.

The library itself does not use __COUNTER__; all diagnostics originate in
vendored Doctest (DOCTEST_ANONYMOUS, used by TEST_CASE and SECTION).

KBSandmanon 78821cd9c2 docs: document standards compliance and parse() vs operator>> strictness (#5326)
* docs: document RFC 8259 / JSONTestSuite compliance and parse() vs operator>> strictness

The compliance story lived only in tests/src/unit-testsuites.cpp, so
drive-by comparisons kept claiming the library "does not fully pass
JSONTestSuite". Make it discoverable:

- README: add a "Standards compliance" note stating that both nst
  JSONTestSuite revisions run in CI, that all mandatory y_/n_ cases pass
  through the strict parse() entry point, and listing the deliberate
  implementation-defined i_ choices (unbounded nesting, silent BOM
  stripping, noncharacters forwarded, strict rejection of invalid UTF-8
  and lone surrogates, out_of_range.406 on numeric overflow).
- features/parsing: add a "Strictness and trailing data" section
  documenting that parse() is strict and rejects trailing data while
  operator>> follows relaxed iostream semantics (parses one value and
  leaves the stream positioned after it) -- the single place a naive
  test yields a "non-compliant" result.

Documentation only; no parser behavior change. Closes #5290.

* docs: correct test-data vendoring and parse()/operator>> claims per review

- README: the JSONTestSuite data is downloaded from nlohmann/json_test_data at
  configure time, not vendored/committed; say so.
- README: only the updated suite runs y_ and n_ cases through strict parse();
  the original suite's y_ cases go through operator>>. Narrow the claim.
- parsing/index.md and operator_gtgt.md: note that operator>> consumes a number's
  terminating byte, so concatenated numbers must be whitespace-separated (1 2
  works, 1true does not); structural and literal values are unaffected.
