AMDBTX v1.1.6 LuckyPool Sparse Job Fix

• Handles LuckyPool job messages that omit nonceBits by preserving the prior suffix width across job/height changes.\n- Adds a fallback that infers common LuckyPool suffix widths from aligned nonce_start values, so a sparse job cannot revert submit to a full 64-bit nonce.\n- Logs LuckyPool nonce_bits on each job for easier diagnosis.\n- Updates installer defaults to amdbtx_miner-1.1.6-py3-none-any.whl with SHA256 370777d3a8c77c118cc8b52417d3db8195090b91e1b87bee2627867442ec6ad0.\n\nVerification: Windows and WSL compileall passed; direct sparse-job check converts full nonce 1a35890093a6bdf4 to suffix 0093a6bdf4.
