Add gs1=True flag to AztecCode, AztecCode.from_preset, find_optimal_sequence, and find_suitable_matrix_size. When enabled, prepends FLG(0) (ISO 24778 §7) as the first encoded character so industrial scanners (Zebra, Honeywell, DataLogic) prefix decoded output with ]z3 for GS1 AI routing in WMS/ERP. - 4 new tests in test_gs1.py verifying FLG(0) is first in sequence - CONFORMANCE.md: evidence report with scanner compatibility matrix - README: GS1 2027 compliance section and API reference update - CHANGELOG: v1.2.0 entry - pyproject.toml: gs1-2027/gs1-compliant/gs1-aztec keywords Co-Authored-By: Riafy agent <benny@riafy.me>
