Enable -Werror for GCC/Clang and /WX for MSVC to enforce warning-free
builds. Fix wchar_t-to-char narrowing conversion in chaiscript_windows.hpp
by using explicit static_cast. Replace deprecated std::wstring_convert in
chaiscript_parser.hpp with direct static_cast. Add noexcept to JSON default
constructor, and mark intentionally unused parameters with [[maybe_unused]].

* Fix#571: Add per-instance IO redirection via set_print_handler/set_println_handler
The print_string and println_string functions were previously registered as static
functions writing directly to stdout, making it impossible to redirect ChaiScript
output to custom destinations (e.g., GUI windows, loggers, or buffers). This moves
their registration from Bootstrap::bootstrap() to ChaiScript_Basic::build_eval_system()
as lambdas that dispatch through configurable std::function handlers, allowing each
ChaiScript instance to independently redirect its output via set_print_handler() and
set_println_handler().

* Address review: add IO redirection section to cheatsheet
Documents set_print_handler() and set_println_handler() with usage
examples for GUI embedding and output capture.

* Address review: define println in terms of print, expose set_print_handler to ChaiScript
Remove separate println_handler — println_string now dispatches through the
single print handler with a newline appended. Only set_print_handler is
needed to redirect all output. The set_print_handler function is also
registered in the ChaiScript engine, so scripts can capture and redirect
their own output.

* Address review: populate null print handler when No_IO is set
When No_IO is active, the default m_print_handler is now a no-op instead
of writing to stdout. The stdout handler is only installed when No_IO is
not set. Users can still override the handler via set_print_handler()
even with No_IO enabled.

* Fix#655: Join async threads before engine destruction to prevent heap-use-after-free
Issues #632 and #636 (PRs #651 and #653) both stem from the same root cause: async
threads spawned via async() can outlive the Dispatch_Engine, accessing shared state
(global objects map, type maps) after it has been destroyed. The fix moves async()
registration from the stdlib module into ChaiScript_Basic, where spawned threads are
tracked via Dispatch_Engine. The engine's destructor now joins all outstanding async
threads before destroying shared data structures.

* Fix#256: Expose get_function_objects() and get_scripting_objects() in public API
The ChaiScript_Basic public API only exposed get_locals() for inspecting
runtime state from C++, requiring users to work around this via
chai.eval("get_functions()") to access function objects. Added
get_function_objects() and get_scripting_objects() as public methods on
ChaiScript_Basic, delegating to the existing Dispatch_Engine methods,
matching the pattern already used by get_locals().

ChaiScript inherits from ChaiScript_Basic, so this is good practice.
I also need to be able to inherit from ChaiScript and dynamic cast, which is impossible without this destructor.
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
There are two warnings when compiling with GCC 7.4.1 or clang 5.0.1.
1. warning: explicit by-copy capture of ‘this’ redundant with by-copy capture default
2. warning: typedef ... locally defined but not used [-Wunused-local-typedefs]
This change removes [2] and it compacts the lambda capture clause in [1].
This modifies no logic, it simply adds the keyword `noexcept`
I believe this is 100% correct. It calls methods that are not
guaranteed to be `noexcept`, such as `operator[]` but have
no logically way of throwing.
