New opcode_utils.py maps opcode numbers to names and detects specialized variants using opcode module metadata. Adds normalize_location() and extract_lineno() helpers to collector base for uniform location handling. CLI gains --opcodes flag, validated against compatible formats (gecko, flamegraph, heatmap, live).
