- nfc-writer is now a native egui window (Windows, macOS, Linux); the web
version moves to the nfc-writer-web binary. Both share src/reader.rs and
src/ndef.rs through the library crate.
- Reader choice no longer depends on the ACR1252U's Windows naming: skip SAM
slots, prefer contactless names (PICC/Contactless/NFC/CL), then a reader
with a card present; NFC_READER forces one by name substring.
- ATR via SCardStatus instead of SCardGetAttrib, which macOS lacks.
- Platform-specific "no reader" hints (pcscd/libccid on Linux, ACS driver on
macOS); Thai fallback font for the GUI from the system fonts.
- Clippy clean for x86_64-pc-windows-msvc, x86_64-unknown-linux-gnu and
aarch64-apple-darwin; README with per-OS setup and a test matrix.
