Resolved conflicts in unittests/compiled_tests.cpp where upstream
clang-formatted the "Typed catch with no match" test cases while this
branch updated the expected exception type to chaiscript::exception::eval_error
(the new wrapping behavior introduced by this PR). Kept the eval_error
expectation and applied upstream's clang-format style.

Merged origin/develop into the branch. Git auto-merged all files
(chaiscript_common.hpp, chaiscript_engine.hpp, chaiscript_eval.hpp,
compiled_tests.cpp) without conflicts. Build succeeds and all 391
tests pass.

* Fix#690: Apply clang-format consistently with CI
Applied clang-format-19 to all source files to enforce consistent
formatting according to the existing .clang-format configuration.
Added auto-clang-format GitHub Actions workflow (from
cpp-best-practices/cmake_template) that runs on pull requests to
automatically format and commit any style violations going forward.

Add a customizable file reader callback to ChaiScript_Basic, following
the same pattern as set_print_handler. When set, the callback is invoked
instead of the default filesystem read, enabling use cases like encrypted
files, in-memory virtual filesystems, or platform-specific file access
(e.g., Android assets). The callback is settable from both C++ and
ChaiScript.

- Catch Boxed_Value in AST_Node_Impl::eval() and wrap in eval_error so
call stack accumulates as the exception propagates through the AST chain
- Add eval_error constructor accepting filename + Boxed_Value
- Populate filename on wrapped eval_error in chaiscript_engine::eval()
- Extract original boxed value in Try_AST_Node for script try/catch semantics
- Unwrap boxed value in internal_eval/internal_eval_file to preserve
script-level exception identity across nested eval() calls
- Add tests for call stack presence, filename population, and
exception_specification backward compatibility

eval_error now stores the original Boxed_Value from script-thrown exceptions,
accessible via has_boxed_value() and boxed_value(). The new rethrow_typed<Types...>(engine)
method provides auto-unboxing without requiring exception_specification to be passed to eval().
This delivers the API simplification envisioned in issue #63: users can catch eval_error,
inspect the call stack, and rethrow as typed exceptions in a single catch block.

* Fix#552: Support nested namespaces via dotted names
Namespaces can now be nested using dotted name syntax, both from C++
(register_namespace(gen, "constants.si")) and from script
(namespace("constants.si")). Parent namespaces are auto-registered when
absent, and child namespaces are automatically nested into their parent
on import. This allows clean hierarchical organization like
constants.si.mu_B instead of flat names like constants_si.

* Address review: use :: instead of . as nested namespace separator
Switch from dotted names (e.g. "constants.si") to C++-style ::
separator (e.g. "constants::si") for nested namespace declarations,
both in the C++ API (register_namespace) and in script (namespace()).
The original implementation used . because namespace members are
accessed via dot notation at runtime (constants.si.mu_B), making the
declaration separator match the access syntax. However, :: is more
consistent with C++ namespace conventions and aligns with ChaiScript's
existing use of :: for method (def Class::method) and attribute
(attr Class::attr) declarations.
Member access in scripts remains dot-based (constants.si.mu_B) since
that is ChaiScript's member access operator.

* Address review: C++-style namespace scoping and block declarations
Add :: scope resolution operator for member access (ns::func works
like ns.func). Add block namespace declarations:
namespace x::y { def func() { ... } }
Functions and variables declared inside a namespace block are added
as members of the namespace, accessible via :: or dot notation.
Namespaces can be reopened to add more members, matching C++ behavior.

* Address review: extract shared make_proxy_function from Def_AST_Node
Namespace_Block_AST_Node was duplicating the entire proxy function
creation logic from Def_AST_Node::eval_internal. Extract a static
make_proxy_function helper so both nodes share the same code path,
eliminating fragile duplication that would drift if Def handling changes.

* Address review: reject non-declaration statements inside namespace blocks
Only def, var, auto, and global declarations are now allowed inside
namespace { } blocks. Arbitrary expressions, assignments, and function
calls are rejected with an eval_error. Added compiled tests verifying
that expressions, function calls, and assignments are rejected.

eval_error now inherits from both std::runtime_error and std::nested_exception,
enabling users to access the original exception via rethrow_nested() or
nested_ptr(). The engine's eval() method wraps uncaught Boxed_Value exceptions
in eval_error, nesting the original Boxed_Value so it can be recovered.
exception_specification continues to work for typed exception unboxing.

* 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: 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].
