Since presym is now mandatory, mruby.h includes presym.h so that
MRB_SYM() macros are available everywhere without explicit include.
Remove redundant #include <mruby/presym.h> from all source files.

ROM method tables used static mrb_mt_tbl variables shared
across the process. The next pointer in each wrapper was
mutated by mrb_mt_init_rom(), causing cross-state
contamination when multiple mrb_state instances existed.
Allocate mrb_mt_tbl wrappers per-state via mrb_malloc().
The const mrb_mt_entry[] arrays remain static and shared.
Wrappers are tracked in mrb->rom_mt and freed at mrb_close().
Remove MRB_MT_ROM_TAB macro; add MRB_MT_INIT_ROM macro that
auto-computes size and calls the new mrb_mt_init_rom().

Restore MRB_ARGS_* argument specs and ISO section comments to all
709 ROM method table entries. The aspec is encoded in bits 4-27 of
the flags field; MRB_MT_NOARG is now auto-derived from aspec==0.
Add MRB_MT_ENTRY_PRIVATE() macro for private methods (53 entries)
and MRB_MT_ASPEC() accessor for extracting aspec from flags.

Since ROM table entries are always C functions, have the
MRB_MT_ENTRY() macro set MRB_MT_FUNC automatically. This
simplifies entry definitions across all 32 source files.

Replace binary search with linear scan in mt_get(), mt_put(),
mt_del(), mt_chain_has(), and mrb_mt_foreach(). The method cache
makes repeated lookups O(1), so linear scan on cache misses is
acceptable.
This removes the sorting requirement, allowing ROM entry arrays
to be declared const. On embedded systems, const static data
resides in flash/ROM instead of RAM, saving ~8.4KB for ~700
method entries on 32-bit MCUs.

Replace the parallel-arrays (struct-of-arrays) ROM method table
layout with an array-of-structs layout where each mrb_mt_entry
bundles its function pointer and symbol key together.
New MRB_MT_ENTRY() and MRB_MT_ROM_TAB() macros simplify ROM table
definitions from a 3-part pattern (SIZE define + anonymous struct +
mrb_mt_tbl) to a 2-part pattern (entries array + mrb_mt_tbl).
Internal mt_* functions in class.c are simplified: single memmove/
memcpy operations replace paired key+value operations.

CRuby's Hash#deconstruct_keys simply returns self regardless of
arguments. The mruby-hash-ext version filtered keys, which was
unnecessary since the compiler accesses individual keys via []
after calling deconstruct_keys. The Ruby implementation in
mrblib/hash.rb (returning self) is sufficient and CRuby-compatible.

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.

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.

This commit introduces `Hash#slice!`, which removes key-value pairs from a
hash, keeping only the ones specified in the arguments. The removed pairs
are returned as a new hash.

Replace Ruby implementation with C version for better performance.
Handles all argument forms: multiple args, hash copy, array of arrays.
Supports subclasses and maintains full compatibility with existing tests.

The "a"/"*" specifier of the `mrb_get_args()` function will now return `const mrb_value *`.
This is because it is difficult for the caller to check if it is an array object and write-barrier if necessary.
And it requires calling `mrb_ary_modify()` on the unmodified array object, which is also difficult (this is similar to #5087).
src/hash.c:
- mrb_hash_(aget|aset|dup|delete): internal linkage
- remove documentation of methods which are not implemented (in here)
- remove #assoc; unused, not in ISO spec
- remove #rassoc: same, implementation is also wrong
hash-ext mrbgem:
- remove header "mruby/khash.h"
- remove mrb_hash_values_at (move code into hash_values_at, i: long -> int)
- less whitespace in gem_init function
- reduce compile time by a little bit (full-core: ~0.7s for me)
- thanks to 'include-what-you-use' for some help
- include Standard C header files before any other (coding style)
