mrb_ccontext functions are implemented in mruby-compiler (y.tab.c),
causing linker errors when the compiler is excluded from the build.
Replace with mrb_load_irep_file() which is in core (src/load.c).
Also fix incorrect *argv in error message and remove dead fname field.

The `mrb` command executes only precompiled RiteBinary (.mrb) files
without depending on mruby-compiler. This enables smaller binaries
for embedded deployments where scripts are precompiled on a
development machine.

ENV is a plain Object with singleton methods and Enumerable,
matching CRuby's behavior. C methods wrap getenv/setenv/unsetenv
with platform support for POSIX, macOS, and Windows.

MPZ_CTX_INIT used a compound literal with designated initializers:
mpz_ctx_t ctx##_struct = ((mpz_ctx_t){.mrb = ..., .pool = ...});
Both features are C99-only, and are not accepted by legacy C++
compilers (notably gcc 4.x) when mruby is pulled into a C++
translation unit via the -cxx.cxx wrapper.
Replace with plain member assignment so the macro expands to code
that is valid under C89/C++98 as well.

Compress the 24-bit aspec into 13 free flag bits on RProc (bits 0-6
and 14-19) when wrapping cfunc methods. Field widths: req/opt 3 bits
(max 7), post/key 2 bits (max 3), rest/kdict/block 1 bit each. Values
exceeding the compressed range are clamped and rest is forced to 1.
This enables Proc#arity and Proc#parameters to return correct results
for cfunc-backed Procs (e.g. from Method#to_proc) with zero memory
overhead -- no struct change needed.
Closes#6764
mrb_str_format captured raw C pointers (p, end) into the format
string's buffer before the main loop. The %s and %p specifiers call
to_s and inspect, which can invoke Ruby code that mutates the format
string via String#replace, freeing or reallocating its buffer. The
loop then continued iterating with dangling pointers, reading freed
memory and potentially leaking adjacent heap contents into the result.
Duplicate the format string with mrb_str_dup() before the loop. This
is O(1) because mrb_str_dup shares the underlying buffer; if the
original is later mutated via String#replace, str_replace decrements
the shared refcount, leaving our duplicate's buffer intact.

String#prepend(s, s) read RSTRING_LEN(argv[i]) in the copy loop after
mrb_str_resize had already updated the receiver's length, causing the
memcpy to write past the allocated buffer.
Detect self-references with mrb_obj_eq() and read from the memmoved
original data at p + total_prepend_len using the captured self_len.
This also handles mixed cases like s.prepend("X", s) where earlier
writes would otherwise corrupt the source of later reads.

The "d" directive in `mrb_get_args()` can be used as an alternative.
Furthermore, NULL checking is unnecessary for the following reasons:
- Incomplete objects from `ary_combination_init()` are not passed to the caller and are garbage collected when `ObjectSpace.each_object` is called, so they are never retrieved
- Even if `state.clone` is called, the `RData::type` of the cloned object is set to NULL, so it is rejected by `mrb_get_args()`
The s = self workaround and XXX comment in recvfrom_nonblock date back
to the initial import of mruby-socket. The underlying bug where self
became a SystemcallException inside ensure blocks has since been fixed.
Verified that self correctly refers to the socket object in ensure
blocks after exceptions from recvfrom.
Change the grammar rule for tLPAREN_ARG from accepting only a
single stmt to accepting compstmt. This allows compound
statements with semicolons inside parenthesized arguments when
the parenthesis is preceded by a space, e.g., `p (f1; f2)`.
This matches the behavior of CRuby 3.3+.
Fixes#6766.

When the block passed to Lazy#flat_map returns a non-enumerable value
(e.g. an Integer), mruby raised NoMethodError because it unconditionally
called #each on the result. CRuby yields non-enumerable values directly.
Use respond_to?(:each) to match CRuby behavior: iterate enumerable
results, yield non-enumerable results as-is.
With `rake -m`, the C compiler can start reading a partially-written
gem_test.c before generation completes. Write to a .tmp file first,
then rename to the final path.

Several methods defined in mruby-array-ext are written in C and may call `mrb_vm_exec()`.
If array objects are modified on the Ruby side, problems may arise in subsequent processing.
- Using objects that have been removed from the array and garbage collected
- Using pointers or array lengths that have become invalid due to changes to the array object
- Modifying the contents of a shared array object directly

Replace `__product_group` method with `__product_generate` and `__product_next`.
This change eliminates the need for Ruby to perform internal state calculations, allowing it to simply receive the results.
case/in without else clause now raises NoMatchingPatternError
when no pattern matches, matching CRuby behavior. Fixes#6741.

Apply the same chunking strategy used for regular array literals
to %w() and %i() literal arrays in gen_literal_array(). Fixes#6740.

Array literals were being built by loading all elements into registers
before constructing the array, requiring nregs proportional to the array
size (e.g. nregs=99 for 100 elements). This exceeds mruby/c's register
limit. Restore 3.4-era chunking at GEN_LIT_ARY_MAX (64) elements.

The old name referred to "truncation" of float precision, which no
longer happens with rotation encoding. The new name describes the
actual behavior: disabling inline float encoding in word boxing.
The old name is kept as an obsolete alias for backward compatibility.
