- buildInt: parse once as unsigned long long (input is never negative),
strip suffixes with remove_suffix, eliminate two-pass fallback path
- json.hpp parse_number: scan number boundaries in-place, call from_chars
directly on the string range — no intermediate strings or std::pow
- parse_num: remove dead integral overload, collapse to single template
- Remove unused <cmath> includes from both files

The custom parse_num floating-point implementation produced slightly
different results from the C++ compiler's own literal parsing (e.g.
1.1e-4 was off by a few ULPs). Replace it with std::from_chars which
is locale-independent and matches compiler precision exactly. Also
migrate integer parsing in buildInt from std::stoll/stoull to
std::from_chars, fix the JSON number parser to pass the full numeric
string to from_chars instead of splitting mantissa/exponent and using
std::pow, and update parse_string to use from_chars for arithmetic types.

The Return() parser function called Operator() to parse the return value,
which only handles arithmetic/logical operators but not assignments. Changed
it to call Equation(), which wraps Operator() and adds assignment parsing.
This is consistent with how If, For, and function argument parsing already
work. Enables `return foo = 5`, `return x += 1`, etc.

The saw_eol variable in Class_Statements() was initialized to true and
only ever set back to true, making the "missing line separator" check
unreachable. The fix separates Def (block statement ending with }) from
Var_Decl (simple statement) so that Var_Decl sets saw_eol to false,
matching the pattern used in Statements() for simple expressions.

* Fix#17: Add const local variable support to ChaiScript
Adds `const var`, `const auto`, and `const` as variable declaration
syntax that creates immutable local variables. A const_override flag
on Boxed_Value enables script-level constness without changing the
C++ type system integration. The parser, optimizer, and evaluator
are extended with Const_Var_Decl and Const_Assign_Decl AST nodes
that mirror their non-const counterparts but mark the value as const
after initialization.

* Address review: remove const_override, set const flag directly on Type_Info
Replace the m_const_override bool on Boxed_Value::Data with a
Type_Info::make_const() method that sets the const bit in m_flags
directly. This ensures constness is visible everywhere consistently,
including places that check get_type_info().is_const() directly.

* Fix#201: Add class inheritance support with Derived : Base syntax
Classes can now inherit methods and attributes from a base class using
C++-style syntax: `class Derived : Base { ... }`. Base class methods and
attributes are automatically available on derived objects. Derived classes
can override base methods by defining a method with the same name.
Inheritance relationships are tracked to support proper type matching
in the dispatch system.

* Address review: use implicit derived-to-base matching instead of copying base class functions
Instead of copying all base class methods/attributes into derived classes,
make the type matching system recognize inheritance relationships. Base class
methods now naturally match derived objects through dynamic_object_typename_match,
and dispatch ordering ensures derived overrides are preferred over base methods.
This is simpler (net -25 lines) and avoids duplicating function registrations.

* Add tests for passing derived objects to functions expecting Base
Tests cover: free functions calling base methods on derived objects,
polymorphic dispatch through containers, base attribute access on
derived objects, and multi-level inheritance (GrandChild : Derived : Base).

* Add typed parameter tests for class inheritance
Use typed function signatures (e.g., `def call_do_something(Base obj)`)
instead of untyped parameters to test that derived objects are accepted
by functions expecting a base type, with correct polymorphic dispatch.

Add C++11-style raw string literals (R"delimiter(content)delimiter") to
ChaiScript. Raw strings do not process escape sequences or perform string
interpolation, solving the issue where base85 encoded data containing ${
sequences would trigger unwanted instring_eval. The implementation adds
Raw_String_() and Raw_String() parser functions and hooks them into the
expression parser.

I initially tried to use the existing .clang-format file,
but it does not match the code style (at least with clang-format 11)
and the formatting is not consistent across files.
Therefore, I decided to rewrite the .clang-format with some personal
preferences.
Used command
find . -iname "*.hpp" -o -iname "*.cpp" | xargs clang-format -i -style=file
