port(2P step 2): ScriptLib/PythonLauncher on the embedded interpreter

Link mtpython into port_logic and copy 40250's ScriptLib launcher across: PythonLauncher, PythonUtils and PythonMarshal, plus the 12 forwarding headers that make its `#include <Python-2.7/*>` lines compile unchanged. symtable.h forward-declares mod_ty rather than including Python-ast.h, whose one-word macros (Delete, Module, Set, Print) collide with EterLib/Pool.h — the same clash 40250 sidestepped by commenting out PySymtable_Build. Two `// PORT:` edits: `unsigned char(val)` is an MSVC extension (PythonUtils.cpp, twice), and PyObject_AsCharBuffer wants a Py_ssize_t* (TraceFunc). port_python_launcher_test drives the launcher in the order UserInterface.cpp does (:241-434): Create(), __DEBUG__/__COMMAND_LINE__, TRUE/FALSE, a CRLF script through RunMemoryTextFile, a .pyc through RunCompiledFile, then RunFile reading system.py out of the real pack. It stops at `ImportError: No module named app`, i.e. the first C++ module RunMainScript registers — that is the 2V0 slice, and the stdlib behind it is step 3. The host flags (Py_NoSiteFlag and friends) sit in the test for now; step 3 moves them into the platform layer. port-map statuses are set only for what the test actually executes: 10 of 12 launcher functions and 4 of 11 marshal ones (the small-.pyc path delegates to CPython's own reader, so the ported r_object stays unreached). PythonUtils compiles but nothing calls it until the binding modules arrive, so it stays TODO. Windows has no mtpython yet, so port_logic drops ScriptLib and the shims there. Tests: macOS ctest 27/27 incl. port.python_launcher; port_logic (with ScriptLib) also compiles for android arm64 (NDK API 24) and ios arm64. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
