* fix: change float format specifier in Object.to_format
Fix the float format specifier in Object.to_format. If there is a float
stored in a Object such as 3.14, it would be printed out as 3 because
the format specifier is %d but should be %g.
* fix: print nan in floatformat
Fix floatformat to print 'nan' if float is nan. Currently,
io::printn(float.nan) will produce 'inf' instead of 'nan'.
Fix a memory leak in HashMap.key_new_list(). The custom memory allocator
will not be used, since key_new_list() will call HashMap.copy_keys()
without passing the memory allocator along. Hence, HashMap.copy_keys()
will allocate on the heap and these memory blocks will not be freed.
To fix this, pass the custom allocator to HashMap.copy_keys(). Also,
since HashMap.key_new_list() is deprecated anyways, replace it by
HashMap.copy_keys().
Affected from this leak is Object.to_format() from
std::collection::object (for an ObjectInternalMap) which is used in the
JSON parser.
The tests for the JSON parser show the memory leak:
$ c3c compile-test test/unit/stdlib/encoding
$ valgrind --leak-check=yes ./testrun

Removing non-present keys is a supported operation on HashMaps,
and most other operations are well-defined on uninitialized
HashMaps.
Currently, removing any key on an uninitialized HashMap will
result in an 'Array index out of bounds' error.
This change guards against such a case.
Upgrade of mingw in CI. Fix problems using reflection on interface types #1203. Improved debug information on defer. $foreach doesn't create an implicit syntactic scope.
Error if `@if` depends on `@if`. Updated Linux stacktrace. Fix of default argument stacktrace. Allow linking libraries directly by file path. Improve inlining warning messages. Added `index_of_char_from`. Compiler crash using enum nameof from different module #1205. Removed unused fields in find_msvc. Use vswhere to find msvc. Update tests for LLVM 19
