NFCraft 0.1.1

On-device fixes verified on real NTAG213 and MIFARE Classic 1K.

Fixed

• Write NDEF to factory-blank Type 2 tags that expose neither Ndef nor NdefFormatable (raw CC + TLV via the page-level engine).
• Read NDEF back correctly (dropped FLAG_READER_SKIP_NDEF_CHECK, which left Ndef.get() null).
• MIFARE Classic identification (ATQA/SAK), chip identification tuning.
• Crash-hardening across the IO path (dump no longer crashes on tag loss).

Verified live

Chip ID (NTAG213, Classic 1K), secp128r1 ECDSA originality-signature verification on genuine NXP silicon, write->read loop, and memory dump — all on-device.
