* Add missing headers to BUILD.bazel and make its generator reproduce it
The "json" cc_library did not list three headers that the library
includes:
- detail/meta/logic.hpp (added in #5016, included by from_json.hpp)
- detail/input/number_parse.hpp (added in #5283, included by lexer.hpp)
- detail/input/string_scan.hpp (added in #5283, included by lexer.hpp
and serializer.hpp)
Bazel's sandbox only exposes declared headers, so any target depending
on @nlohmann_json//:json and including <nlohmann/json.hpp> failed with
"'nlohmann/detail/meta/logic.hpp' file not found".
The file could not simply be regenerated, because the generator behind
"make BUILD.bazel" was stale: it wrote only the "json" cc_library and
dropped the load() statements, the license block, and the
"singleheader-json" target that were added by hand in #4584. The
generator now emits the complete file, so its output differs from the
previous BUILD.bazel only by the three headers. It also resolves the
glob against the project root instead of the working directory and
sorts the list explicitly.
"make BUILD.bazel" is now phony: in a fresh checkout, BUILD.bazel is
not older than the headers, so make considered it up to date, and a
removed header would never trigger a rebuild. "make check-amalgamation"
also checks that BUILD.bazel is up to date.

* Check in CI that BUILD.bazel is up to date
The "Check amalgamation" workflow now also regenerates BUILD.bazel, so a
pull request that adds, renames, or removes a header without updating
the Bazel header list fails, and the attached amalgamation.patch
contains the fix. The failure comment and the contribution guidelines
mention the new check, and the comment now links to the existing
"Amalgamate the source code" section instead of the "Files to change"
anchor that was removed in #4560.
