Add Python 3.14 bytecode support and improve 3.13/3.14 recovery

[Techuouo520]

This PR adds Python 3.14 bytecode support and improves recovery for newer Python 3.13/3.14 bytecode patterns.

Changes

• Add Python 3.14 magic number recognition.
• Add Python 3.14 opcode metadata/mapping.
• Enable Python 3.14 in supported version checks.
• Add Python 3.14 marshal slice object support.
• Add cache-aware instruction offset handling for Python 3.12+ jump targets.
• Improve pycdas operand formatting for newer opcodes.
• Improve best-effort pycdc recovery for unsupported or partially supported bytecode.

Opcode Support / Improvements

Added or improved handling for:

• CALL_KW
• INSTRUMENTED_CALL_KW
• CALL_FUNCTION_EX
• INSTRUMENTED_CALL_FUNCTION_EX
• MAKE_FUNCTION
• SET_FUNCTION_ATTRIBUTE
• TO_BOOL
• FORMAT_SIMPLE
• FORMAT_WITH_SPEC
• CONVERT_VALUE
• MAKE_CELL
• COPY_FREE_VARS
• LOAD_FAST_CHECK
• LOAD_FAST_AND_CLEAR
• LOAD_FAST_BORROW
• LOAD_FAST_BORROW_LOAD_FAST_BORROW
• LOAD_SMALL_INT
• LOAD_COMMON_CONSTANT
• LOAD_SPECIAL
• STORE_FAST_LOAD_FAST
• STORE_FAST_STORE_FAST
• MAP_ADD
• DICT_UPDATE
• DICT_MERGE
• CALL_INTRINSIC_1
• CALL_INTRINSIC_2
• POP_ITER
• NOT_TAKEN
• END_ASYNC_FOR
• EXTENDED_ARG
• Python 3.14 instrumented opcode variants

Fixes

• Fix Python 3.14 .pyc files being reported as unknown magic / unsupported version.
• Fix Python 3.11+ CALL / CALL_KW NULL self-slot handling.
• Fix keyword-call recovery such as json.dumps(..., ensure_ascii=False).
• Fix Python 3.13 MAKE_FUNCTION handling.
• Fix Python 3.13 SET_FUNCTION_ATTRIBUTE handling.
• Fix Python 3.14 BINARY_OP subscription handling.
• Fix relative jump target calculation around inline cache entries.
• Improve fallback behavior for unsupported newer bytecode.
• Improve Python 3.9/3.10 try / except recovery around JUMP_IF_NOT_EXC_MATCH.
• Skip synthetic except X as e cleanup patterns such as e = None; del e.
• Increase MSVC pycdc.exe stack reserve to better handle deeply nested / obfuscated bytecode.

Tests

• Added a Python 3.13 CALL_KW regression test.
• Tested Python 3.14 .pyc recognition and disassembly.
• Tested best-effort decompilation on Python 3.14-generated .pyc files.

Notes

Python 3.14 source decompilation is still best-effort. Complex or heavily obfuscated control flow may still produce imperfect source output or placeholder conditions, but the files should now be recognized and disassembled instead of failing at magic/version detection.
