dropfield waited on a reply the firmware never sends (bare hf_field_off();break;) -> 2s stall + raise; use send_ng_no_response. hf.sniff under-sent the 10-byte {u32,u32,u8,u8} struct and mis-parsed the uint16 reply. hw.standalone sent an empty payload for a {arg,mlen,mode[10]} struct and blocked; pack it + fire-and-forget. Pre-existing, independent of rebase.

CMD_MEASURE_ANTENNA_TUNING_HF requires a 1-byte mode arg (firmware rejects length!=1 with EINVARG) and returns the voltage as uint16, not uint32. tune() sent no arg (empty reply -> 0 mV) and parsed <I. Now sends mode 1/2/3 (START/MEASURE/STOP) and parses <H. Verified vs firmware appmain.c handler; C client reads the same ~15V on this firmware.

Phase 1 of package refactor. Moves all source modules into pm3py/core/
with file renames (hf_14a→hf_iso14a, hf_15→hf_iso15, hf_mf→hf_mfc)
and client attribute normalization (hf.a14→hf.iso14a, hf.mf→hf.mfc).
pm3py/__init__.py re-exports from core for backward compat.
