Add Python 3.11/3.12 opcode handlers to reduce decompilation failures

[gustavomfc]

No-op prologue/bookkeeping opcodes:

• MAKE_CELL_A: closure cell initialization (Python 3.11+)
• COPY_FREE_VARS_A: copies free vars into frame at function entry (3.11+)
• RETURN_GENERATOR: marks a function as a generator (3.12)

Stack/call opcodes:

• YIELD_VALUE_A: generator yield with stack-depth operand (3.12)
• CALL_FUNCTION_EX_A / INSTRUMENTED_CALL_FUNCTION_EX_A: func(*args, **kwargs)
• LOAD_SUPER_ATTR_A: super().attr access (3.12 specialization)
• LOAD_FROM_DICT_OR_DEREF_A: closure variable load (3.12)

Comprehension opcodes:

• SET_ADD_A: set comprehension element append
• MAP_ADD_A: dict comprehension key/value append
• DICT_UPDATE_A: in-place dict merge (like SET_UPDATE_A for dicts)

Other opcodes:

• LOAD_ASSERTION_ERROR: pushes AssertionError class (used in assert stmts)
• DICT_MERGE_A: merges **kwargs mapping into accumulator dict
• CALL_INTRINSIC_1_A: Python-internal intrinsic functions (pass-through)
• POP_JUMP_IF_NONE_A / POP_JUMP_IF_NOT_NONE_A: None-checking conditional jumps
• LOAD_FAST_CHECK_A / LOAD_FAST_AND_CLEAR_A: variants of LOAD_FAST

Bug fixes:

• Restore accidentally-removed 'case Pyc::LOAD_ATTR_A:' label that was clobbered when inserting the DICT_MERGE_A handler
• Handle NODE_TUPLE (and other unexpected node types) inside f-string (NODE_JOINEDSTR) value lists by wrapping them in { } instead of emitting 'Unsupported node type' and marking cleanBuild=false
