v0.1.0

First Arduino Library Manager submission.

Highlights

• RC522 driver audited end-to-end. SPI (hardware and software-bit-bang) and I2C transports, full magic-tag safety, multi-sector dump, type-aware card detection (Classic 1K / 4K / Mini, Ultralight, NTAG213/215/216).
• Safe UID rewriting. writeBlock refuses block 0 and sector trailers by default; setUid defaults to a dry-run preview. commit=true backs up block 0, writes, halts, re-detects and verifies the UID.
• Cross-platform. AVR / SAMD / ESP32 / ESP8266 / nRF52 / STM32 / RP2040 / Renesas RA, one source tree.
