* 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.
