Port 5 complex opcodes to hybrid z-machine interpreter
Implement op_sread (text input), op_save/restore (file I/O stubs),
op_restart (exception-based reset), op_input_stream and op_sound_effect
(no-op stubs). Add ZCpuRestart exception. All implementations follow TDD
with comprehensive unit tests.

Port 4 medium opcodes to hybrid z-machine interpreter
Implements op_print_addr, op_print_num, op_ret, and op_show_status following
TDD approach with tests first. Each opcode now properly decodes/prints text,
handles signed numbers, returns from routines, or acts as a no-op as appropriate.

Port 10 object tree opcodes to hybrid z-machine interpreter
Implemented 10 opcodes for object tree manipulation: get_sibling,
test_attr, set_attr, clear_attr, jin, remove_obj, print_obj,
get_prop_addr, get_next_prop, and get_prop_len.

Added 6 supporting methods to ZObjectParser: set_attribute,
clear_attribute, remove_object, get_property_data_address,
get_next_property, and get_property_length.

Fixed bug in insert_object where sibling chain walk never advanced
the prev pointer, potentially causing infinite loops.

Added 16 unit tests with MockObjectParser to verify CPU opcode
behavior. All tests passing.
