Fixed broken dependency path (../clients/python -> ../client-py). Added strict ruff config. Removed dead meshcore/orac/telemetry justfile recipes (scripts never existed). Applied SIM105 (contextlib.suppress) and I001 (import sorting) lint fixes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
