Rename ~2887 unreadable Procyon-decompiler locals/params (f/f2/fN, n/n2, bl/bl2, nArray, bufferedImage, etc.) across 169 files to context-aware camelCase identifiers (x, y, width, height, alpha, color, sensitivity, etc.). Logic, control flow, field/method names and method signatures (types/arity) are preserved; only local variable and parameter names changed. Co-Authored-By: Claude Opus 4.7 <[email protected]>
