Replace block.call(x) with yield x in core iteration methods to take
advantage of the new OP_BLKCALL optimization. This improves Integer#times
by 13% and Array#each by 7%.
Methods updated:
- Integer#times, Integer#upto, Integer#downto
- Array#each, Array#each_index

Use self.begin/self.end instead of first/last to compute hash for
ranges. The first/last methods raise RangeError for endless/beginless
ranges, but the internal begin/end accessors return nil safely.

Add support for hash patterns in pattern matching expressions:
- {key:} shorthand binds to variable with same name
- {key: pattern} matches key against pattern
- {**rest} captures remaining keys
- {**nil} requires exact match (no extra keys)
- {**} ignores extra keys without capturing
Parser adds new grammar rules (p_hash, p_hash_body, p_hash_elems,
p_hash_elem, p_kwrest) and new_pat_hash() constructor.
Codegen generates code to call deconstruct_keys on the target hash,
then iterates through key-pattern pairs to match each key's value.
Adds Hash#deconstruct_keys method that returns self for pattern matching.

changed block spacing from {|param| to {|param| (space before brace)
for consistency with the most common pattern in the codebase.

added parentheses to all `to_enum` and `super` calls where the return
value is used (returned, assigned, or passed to another method). this
makes the code style consistent with the guideline that method calls
should use parentheses when their return values are consumed.
changes:
- return to_enum :symbol -> return to_enum(:symbol)
- return to_enum :symbol, arg -> return to_enum(:symbol, arg)
- super message, name -> super(message, name)
affected files: 10error.rb, array.rb, enum.rb, hash.rb, kernel.rb,
numeric.rb, range.rb

Modify `Enumerable#hash` to use `__method_recursive?(:hash)` for recursion
detection, preventing infinite loops when hashing self-referencing enumerables.
Add a test case to verify the fix.

Replace XML-style markup tags in comments with markdown equivalents:
- <code>...</code> to `...` (inline code)
- <tt>...</tt> to `...` (teletype/monospace)
- <i>...</i> to *...* (italics/emphasis)
- +...+ to `...` (parameter/variable references)
Updated 80+ files across core source, headers, mrbgems, and libraries
to use consistent markdown formatting in documentation comments.
Handled edge cases including special characters like <=> operators.

Move Hash#eql? implementation from Ruby to C to improve performance and
consistency with other core methods. The C implementation uses mrb_eql
for value comparison, providing proper eql? semantics.

Move Hash#== implementation from Ruby to C to improve performance
and consistency with other core methods. The C implementation
provides the same functionality while being more efficient.

Array#to_a now properly converts subclasses to Array objects. For example,
'class A<Array;end; p A.new(1,2).to_a.class' now returns Array, not A.

The technique is called "double dispatch" (that was popular in
Smalltalk), but it does not work well with mruby. It's slower and
consumes more memory. Even thought `#append_features` defined in ISO
standard (15.2.2.4.11), we decided to remove it. Strictly speaking, it
is mruby limitation. And it should be documented clearly.
When called in combination with a method like `*_eval` or `*_exec` that switches self, `__send__` was passed an object that was not necessarily a symbol as the method name.
This problem was discovered during the #6389 correction process.
It used to check all `start`, `end` and `step`. If either of them are
float number, `#step` iterated over float number. Now we don't check the
type of `end` argument.
- use heap sort (O(1)) instead of merge sort (O(n)) for better space
complexity.
- method implemented in C for better performance
As a result, simple sorting now consumes far less memory and is faster.
Since it's implemented in C, fiber context switching is not allowed from
comparison, but we consider the risk is minimal (no one switches context
in the comparison, right?)
