Long-running checksum cracker for Lofi-12 XT cmtd+0x08.
Strategy: 3 known (image, checksum) pairs let us test each hypothesis fast
with early exit, plus detect CONSTANT-XOR-masked CRCs (stored = crc ^ mask).

Kept for methodology only — do not run expecting new results.
Phase D checksum cracker: 16-bit/ones-complement/chained/DJB2/Murmur batch.
Covers what Phases A-C did not: every candidate must match ALL 3 builds.
Stdlib only, read-only on stock .bin files.
