* feat(artifacts): inventory and extract Intel HEX and Motorola S-record regions
open_binary refused Intel HEX and S-record programming files as an
unsupported format, so inspect_artifact and extract_artifact could not
answer which bytes load at which addresses.
Recognize both encodings by a fully valid first record and decode them
statically into address-contiguous regions, each an inventory entry named
0x<start>-0x<end>.bin and extractable as raw bytes. Root format_metadata
records the encoding and variant, record counts, unique and duplicate
bytes, address bounds, termination, declared start address, S0 header and
validated S5/S6 count. Gaps are never filled; start addresses are declared
facts, not proven entry points.
Checksum, record-type, byte-count, line-length, overlap-conflict, address
wrap and post-termination errors fail closed with the line number; a
missing termination record leaves coverage unknown. Decoding is bounded by
a 128 MiB file ceiling (decoded bytes are at most half the file and are
reserved after the size check) and 65,536 address-discontiguous runs.

* fix(artifacts): refuse Intel HEX extended address records with a non-zero address
* fix(artifacts): bound HEX region copies and retain stream cancellation
