fix(compiler): resolve bitwise not operation on class constants in AOT compilation

- Updated CompilerBase.php to use convertIntExpr for bitwise not operations on variables
- Modified gen_stub.php to always use var_export for default value conversion
- Enhanced object_property test to follow strict type checking with TypeError handling
- Added native property test for bitwise not class constant assignments
- Updated Translator.php to return raw values instead of CValue wrappers for constants
- Improved documentation consistency across project overview files
- Added strict types declaration to property assignment test cases

+TypePHP is a PHP native compilation project. Its `tpc` command is TypePHP Compiler (AOT), which translates PHP source into C++, then compiles and links it into a native binary or a PHP extension. The primary entrypoint boots `src/compiler.php`; that drives `TypePhp\Translator` through a fixed pipeline:
 
 1. `prepare()` scans files, parses ASTs, collects symbols, and topologically sorts PHP files by cross-file symbol usage.
 2. `convert()` turns PHP ASTs into generated `.cc` files while passing through native source files (`.cpp`, `.c`, `.s`, `.m`, `.mm`).
