CPU key-search engine using coincurve for fast EC math, with checkpoint/
resume and sharding support. Verified against solved puzzles demining#20 and #66.
Replace per-key PrivateKey.from_int() scalar multiplication with a single
initial multiplication followed by PublicKey.add() (point + G) each step.
Benchmarked ~4x faster in this environment (verified against selftest and
a live solved-puzzle search) since coincurve's tweak-add path skips the
extra object/validation overhead that from_int() pays per call.
Checkpoint/log files from the 4-shard keyhunt.py run against puzzle 71.
No match found (expected: 2^70 keyspace is not brute-forceable).
These are live process output that changes every few seconds while the
search runs, so tracking them causes constant repo churn. Untrack them
and ignore going forward; the tool itself stays version-controlled.
