* Add missing _winapi functions and fix WinHandle int conversion
Add 13 functions: ReadFile, SetNamedPipeHandleState, CreateFileMapping,
OpenFileMapping, MapViewOfFile, UnmapViewOfFile, VirtualQuerySize,
CopyFile2, ResetEvent, CreateMutex, OpenEventW, LoadLibrary,
_mimetypes_read_windows_registry.
Add constants: INVALID_HANDLE_VALUE, FILE_MAP_READ/WRITE/COPY/EXECUTE.
Change WinHandle integer type from usize to isize so negative values
like INVALID_HANDLE_VALUE (-1) can be passed from Python.
* Align _winapi module with CPython
- Rename winapi.rs to _winapi.rs with #[path] attribute
- Rename CreateMutex to CreateMutexW
- Add missing constants: ERROR_ACCESS_DENIED, ERROR_PRIVILEGE_NOT_HELD,
PROCESS_ALL_ACCESS, 10 STARTF_ constants, LOCALE_NAME_SYSTEM_DEFAULT,
LOCALE_NAME_USER_DEFAULT, COPY_FILE_DIRECTORY
- Fix OpenMutexW return type and ReleaseMutex param type to use WinHandle
* Fix ReadFile/WriteFile overlapped keyword argument
Use FromArgs structs so overlapped parameter can be passed as
a keyword argument (overlapped=True), matching the CPython API.
* Remove extra constants and LoadLibrary not in CPython _winapi
Remove 19 constants (WAIT_ABANDONED, CREATE_ALWAYS, CREATE_NEW,
OPEN_ALWAYS, TRUNCATE_EXISTING, FILE_ATTRIBUTE_NORMAL, 8 FILE_FLAG_*,
3 FILE_SHARE_*, NMPWAIT_NOWAIT, NMPWAIT_USE_DEFAULT_WAIT) and
LoadLibrary function that are not present in CPython's _winapi module.
* Fix utf8_mode default to 0 and add PYTHONUTF8 env var support
Default utf8_mode was incorrectly set to 1, causing text-mode
subprocess to always decode as UTF-8 instead of locale encoding.
Changed default to 0 to match CPython 3.13 behavior on Windows.
Added PYTHONUTF8 environment variable handling with -X utf8 override.
* Fix CopyFile2 to raise proper OSError subclass
Use std::io::Error::from_raw_os_error instead of vm.new_os_error so
that winerror attribute is set and errno-to-exception mapping works
(e.g. ERROR_ACCESS_DENIED → PermissionError).
* Fix syntax_non_utf8 test to not depend on locale encoding
Use explicit encoding='latin-1' so the test works regardless of
the system locale (e.g. C/POSIX locale uses ASCII by default).
* Add compile_bool_op_inner and optimize nested opposite-operator BoolOps to avoid redundant __bool__ calls
When a nested BoolOp has the opposite operator (e.g., `And` inside `Or`),
the inner BoolOp's short-circuit exits are redirected to skip the outer
BoolOp's redundant truth test. This avoids calling `__bool__()` twice on
the same value (e.g., `Test() and False or False` previously called
`Test().__bool__()` twice instead of once).

* Apply clippy and rustfmt
* Apply ruff format
* Refactor compile_bool_op: extract emit_short_circuit_test and unify with compile_bool_op_inner
Reduce code duplication by:
- Extracting the repeated Copy + conditional jump pattern into emit_short_circuit_test
- Merging compile_bool_op and compile_bool_op_inner into a single
compile_bool_op_with_target with an optional short_circuit_target parameter
- Keeping compile_bool_op as a thin wrapper for the public interface

* Add host_env feature for sandbox isolation
Introduce a `host_env` feature flag that gates all host environment
access (filesystem, network, signals, processes). When disabled,
the VM operates in sandbox mode:
- _io module always available; FileIO gated by host_env
- SandboxStdio provides lightweight stdin/stdout/stderr via Rust std::io
- BytesIO/StringIO/BufferedIO/TextIOWrapper work without host_env
- open() returns UnsupportedOperation in sandbox
- stdlib modules (os, socket, signal, etc.) gated by host_env
- CI checks both host_env ON and OFF builds
* Auto-format: ruff check --select I --fix

* Fix sorted() to use __lt__ instead of __gt__
CPython's sort uses __lt__ for comparisons, but RustPython was using
__gt__. This caused issues when only __lt__ was overridden on a
subclass (e.g., NamedTuple with custom __lt__), as it would fall back
to the parent class's comparison instead of using the overridden method.
