Add CMD_HF_SNIFF_STREAM (0x0337) and CMD_HF_SNIFF_STATUS (0x0338) for
fire-and-forget trace streaming during sniff. Unified sniff loop uses
the same proven decode path for both streaming and legacy modes —
streaming replaces LogTrace with ring buffer SNIFF_PUSH/SNIFF_FLUSH.
Firmware features:
- Idle flush: sends buffered trace entries over USB when RF is quiet
for idle_timeout_ms (configurable, default 400ms for 15693)
- Button-toggle: pause/resume sniffing without restarting
- DMA restart on resume for clean decoder state
- BREAK_LOOP support for Python-side session.stop()
- Legacy mode (flags=0) preserved unchanged
Python constants: SNIFF_FLAG_STREAMING, SNIFF_FLAG_BUTTON_TOGGLE,
SNIFF_STATE_STARTED/PAUSED/RESUMED/STOPPED, Cmd.HF_SNIFF_STREAM/STATUS
source activate once, then pm3/pm3 sim/pm3 sniff/pm3 all to launch
REPL with appropriate imports. Uses python -i for reliable startup.

Trace buffer parsing, protocol decoders, NDEF annotation, and
formatting are firmware-level features shared by sniff, sim, and
reader modes — not sniff-specific. Moves these from sniff/ into
trace/. sniff/ retains only SniffSession (orchestration) and
re-exports trace symbols for convenience.

Merges the package refactor (core/ sub-package, normalized naming,
scaffolded sub-packages) while preserving all in-progress sniff
infrastructure. Git rename detection carried WIP changes to new paths.

In-progress work — committing before refactor merge so git rename
detection can carry changes to new file locations.

Phases 2-4 of package refactor. Creates the full directory tree with
__init__.py files per the design doc. Actual code migration from the
sim worktree is a separate effort — models have deep inheritance chains
and auth mixins that need base class extraction first.

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.

- Add table compiler match pattern rules to main CLAUDE.md (was only in worktree)
- Update sim framework description (750+ tests, add DNA/NTAG5 to IC list)
- Update "planned" → "in progress" for Python-driven card sim
- Fix firmware patch size: ~320 lines (was inconsistently ~340 on line 49)
4 tasks: update TableEntry to 120-byte format, compile_nxp_icode,
compile_slix2, wire auto-compile into SimSession.start_15693.

Tested retry-based relay and spin-wait approaches. Relay works
mechanically via retry but is unreliable (reader-dependent).
Spin-wait fails due to USB stack latency. Table is the only
viable mechanism for 15693 custom commands.

Covers: sim_table entry structure with EML actions and group-based
state machine, AES-CMAC for TAM/MAM, native handler access control,
14443-A integration, timing budget analysis.
