changed mrb_open() and mrb_open_core() to return mrb_state with mrb->exc
set (instead of NULL) when initialization fails. this allows callers to
programmatically inspect error details, which is essential for embedded
systems without stderr. return NULL only for true allocation failure.
added MRB_OPEN_SUCCESS(mrb) macro to check initialization success, since
mrb != NULL no longer guarantees success. updated all binary tools
(mruby, mirb, mrdb, mrbtest) to use new pattern: check MRB_OPEN_SUCCESS,
print exception details via mrb_print_error if available, then mrb_close.
mrb_core_init_protect now preserves exception in mrb->exc instead of
printing and clearing it, giving caller control over error handling.
breaking change: callers must use MRB_OPEN_SUCCESS(mrb) or check both
mrb != NULL && mrb->exc == NULL. old NULL-only checks will miss
initialization failures.

dd96afd added const_added hook call to mrb_const_set(), but calling
mrb_funcall_argv() during core initialization (before bootstrapping
completes) fails on bare metal platforms where VM is not fully ready.
skip hook during mrb->bootstrapping phase, matching pattern used in
class.c for method cache clearing.

set_do_flatten allocated temporary kset_t* via kset_init(). when
exceptions were raised during flattening (e.g., from hash function),
temporary kset was never freed. refactored to pass result set directly
and fill in-place. result set object is GC-protected, so exceptions
are handled cleanly without leaks.

kh_is_end() safely checks if an iterator is at the end position,
preventing issues when the hash table is modified during iteration.
replaced direct kset_end() comparisons with kset_is_end() calls
throughout set operations.

during eql? callbacks, array modifications can cause elements in khash to
be freed by GC, leading to use-after-free. create temporary shared copies
of arrays before populating khash to protect elements during callbacks.

add exception handling with MRB_TRY/MRB_CATCH to ensure khash cleanup
when eql? or hash methods raise exceptions. use kh_is_end macro for safe
khash iteration.

when overriding struct#==, array#==, or hash#== with super, the recursion
detection incorrectly treated the super call as a circular reference. this
was caused by commit 5ca2d442 which added recursion detection.
the fix introduces mrb_recursive_func_p that starts from ci[-2] instead of
ci[-1], skipping the immediate parent frame which may be a ruby override
calling super. equality methods (==, eql?) now use this function, while
inspect methods keep using mrb_recursive_method_p for immediate circular
reference detection.

Add arg_error() helper function to replace goto statements used for
error handling. This function is marked with mrb_noreturn attribute
since it calls mrb_raise which never returns.

goto statements used for error handling. These functions are marked
with mrb_noreturn attribute since they call mrb_raise/mrb_sys_fail

allocate ** keyword dictionary register when methods have keyword
arguments (parse.y new_args_tail), broken in commit 26ea71260 during
cons-list to struct migration. reconstruct keyword hash after KEYEND
from extracted keyword local variables so super can access keyword
values. encode block parameter flag in ainfo bit 13 and generate
LOADNIL for block register in codegen_zsuper when parent has keywords
but no block parameter.

The `mrb_obj_as_string()` function can call the `#to_s` method.
String addresses and string lengths obtained outside the `KSET_FOREACH()` loop may become invalid.
The primary reason is to fix an issue that occurs when an element is removed from the khash data during the `KHASH_FOREACH()` loop.
If the value of `kh_end()` becomes smaller than `k` during the loop, it will repeat a meaningless internal loop until an integer overflow occurs.
Restore exception handling for `||=` operator on class variables and constants
that was inadvertently removed in commit 0ca48e24f. When reading an undefined
class variable with GETCV opcode raises NameError, the exception handler
catches it and loads false, allowing the assignment to proceed.

add length check to detect array modification during sort. when realloc()
shrinks an array in-place, it may return the same pointer, defeating the
pointer-only check. the new check catches both pointer changes and length
changes, preventing out-of-bounds access.
the fix captures array pointer and length at the start of each comparison,
then validates both after user code executes. this detects modifications
even when realloc() returns the original pointer.

refactor to use the standard Data_Make_Struct() macro instead of manual
RData allocation and linking. the macro provides automatic zero-initialization
and is more idiomatic.
