Implement specialized modular reduction algorithm for single-limb modulus
to avoid expensive division operations. The optimization uses repeated
division with double-precision arithmetic for multi-limb dividends and
direct modulo operation for single-limb dividends.
Algorithm:
- Single-limb dividend: direct modulo operation (x % m)
- Multi-limb dividend: iterative reduction using double-precision arithmetic
processing limbs from most significant to least significant
Purpose:
- Accelerate common modular arithmetic operations with small moduli
- Reduce computational overhead for cryptographic and mathematical operations
- Improve performance of rational number arithmetic that relies on modular ops
Performance impact:
- Single-limb modulus: ~1.04M ops/sec (6x improvement over general case)
- Maintains correctness for all existing modular arithmetic operations
- Zero impact on large modulus operations (fallback to existing algorithm)

Rename internal functions to follow mruby's snake_case naming convention:
- mrb_struct_initialize_withArg -> mrb_struct_init_with_args
- mrb_struct_initialize_withKw -> mrb_struct_init_with_keywords
Update all function calls to use the new names. This improves code
consistency and follows established mruby naming conventions.

Replace mrb_funcall_id call with direct mrb_ary_join function call
in error message generation to comply with VM callback restrictions.
This prevents re-entrant VM execution which can cause crashes and
undefined behavior, following mruby's policy of avoiding VM callbacks
from C code.

Replace mrb_intern_lit calls with MRB_SYM and MRB_IVSYM macros for
better performance and consistency. Convert mrb_funcall with string
literals to mrb_funcall_id with MRB_SYM for the keyword_init feature
and other method calls.
Key optimizations:
- keyword_init symbol access using MRB_SYM(keyword_init)
- Instance variable access using MRB_IVSYM(__keyword_init__)
- Method calls using mrb_funcall_id with MRB_SYM(join)
This improves runtime performance by avoiding symbol table lookups
for commonly used symbols and follows mruby's presym conventions.

feature added in commit 512d25607b.
Changes include:

usage, including basic usage, partial initialization, and error cases
- struct.c: Updated call-seq documentation for Struct.new to include
keyword_init parameter and added examples of keyword-based struct
creation and initialization

instead of positional arguments, providing a more explicit and
Ruby-like interface for struct initialization.
Examples added:
- Basic keyword initialization with keyword_init: true
- Partial initialization with missing keys defaulting to nil
- Error handling for mixed positional/keyword arguments
- Empty initialization behavior

Fix incomplete digit processing in power-of-2 base string conversion:
- Add handling for remaining bits after processing all limbs
- Ensure all significant bits are converted to digits
- Maintain correct conversion for large numbers with partial bit patterns

converted when the total bit count doesn't align perfectly with the
base's bit width, ensuring complete and correct string representation.

Replace the traditional Euclidean GCD algorithm with Stein's binary GCD algorithm
for improved performance on large numbers:
- Implement binary GCD (Stein's algorithm) avoiding expensive division operations
- Use bit shifts and subtraction instead of modulo operations
- Handle special cases (zero values) efficiently
- Preserve common factors of 2 for correct results
- Maintain full compatibility with existing rational number functionality
Binary GCD is significantly faster for large numbers as it avoids the costly
division operations used in the Euclidean algorithm, using only bit operations,
addition, and subtraction.

Prevent SystemStackError when comparing structs with circular

Array equality methods.

mruby does not provide `begin ... end while cond` that behave at-least-once
loop, like CRuby does. It remains in TODO.md for long time. But finally we have
implemented the behavior.
This commit introduces NODE_BEGIN as a distinct AST node type for
explicit begin...end blocks, separate from NODE_STMTS which represents
general statement sequences. This distinction will be essential for
implementing CRuby-compatible begin...end while/until constructs.
Key changes:
- Added NODE_BEGIN enum in node.h
- Added new_begin() function in parse.y using optimized cons() structure
- Modified begin...end grammar rule to generate NODE_BEGIN nodes
- Added NODE_BEGIN codegen support in codegen.c
- Added NODE_BEGIN to parser dump functionality
NODE_BEGIN uses a simpler cons() structure instead of list2() for
better memory efficiency, as it only contains a single body node.
Co-Authored-By: Claude <noreply@anthropic.com>
Modify new_stmts to flatten unnecessary nesting by returning existing
NODE_STMTS directly instead of wrapping them. This reduces memory usage
and AST complexity when multiple parentheses levels are used.
Before: (((expr1; expr2))) creates nested NODE_STMTS
After: (((expr1; expr2))) creates single NODE_STMTS with statements

Rename NODE_BEGIN to NODE_STMTS to better reflect its purpose as a
container for statement sequences, not specifically begin-end blocks.
This prepares for adding a dedicated node type for explicit begin-end
constructs.
- Rename NODE_BEGIN enum to NODE_STMTS in node.h
- Update all references in parse.y and codegen.c
- Rename new_begin function to new_stmts

This commit adds `call-seq` documentation to the following methods
in `mruby-numeric-ext` to improve code clarity and maintainability:
- `Integer#even?`
- `Integer#odd?`
- `Integer.sqrt`

Additionally, it adds a comment to the internal `isqrt` function
to explain its implementation.

The `XXX` comment in `sprintf.c` suggested that not validating
the number of arguments for positional format specifiers was a bug.
However, CRuby's `sprintf` also ignores extra arguments in this
case, making the existing behavior correct.
This commit removes the confusing comment and the disabled code
block that went with it, clarifying the intended behavior and
cleaning up the code.

The `mruby-hash-ext` gem already had `call-seq` comments for its
public methods, but the internal helper functions `slice_bang_i` and
`hash_key_i` were undocumented.
This commit adds detailed comments to these functions, explaining their
purpose, parameters, and return values. This improves the
maintainability and readability of the code.

Fixed critical resource leaks by pre-allocating mruby objects before system

pre-allocated size cannot fail, moving allocations before socket creation
eliminates all leak potential with minimal code changes.
