Update all disassembly code to use new cgo-based decoder API with stack-allocated instruction structs instead of heap-allocated pointers. Add instruction filtering to skip decoding operations that register tracking doesn't care about, avoiding expensive CGo calls. Key changes: - Replace Decompose with DecomposeInto using stack allocation - Add mayBeTrackedInstruction filter for common tracked ops - Introduce helper functions for safe operand/register access - Fix metaclass pointer index to use caller index for efficiency - Remove root file special-casing in pointer index builder - Add comprehensive unit tests for tracking options and helpers
