description: bounded greedy substitution search (2MB calibration, 60 candidates) + tuned xz

Bounded greedy substitution search: built candidate patterns, iteratively added substitutions only if they reduced xz size on a 2 MB calibration slice (60 candidates evaluated), applied accepted table to full enwik8. archive=24,624,504; decompressor.zip=699; total=24,625,203. Did not beat AutoZip's dict-auto-xz best at 24,564,096. Roundtrip verified.
