Fix #17: Add const variables in ChaiScript (#643)
* 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.

Requested by @lefticus in PR #643 review.
