perf: DEFLATE (puff) + -no-pie -> OF binary 879 KB -> 662 KB (-25%)
Two size wins: - Replace the home-grown LZSS (2.0x) with DEFLATE: mktext gzips the text and strips the gzip container to a raw DEFLATE stream; clectio decompresses it with puff, Mark Adler's public-domain reference inflate (~200 lines, verified byte-identical to gunzip on the OF/EF text, repetitive, random and empty inputs). Text blob 671 KB -> 492 KB (OF), 164 KB -> 132 KB (EF), 2.7x. - Build with -no-pie: clectio is a local CLI reading static embedded data with no attack surface, so it needs no PIE/ASLR. The linker then bakes the string- table pointers in at link time instead of emitting ~57 KB of runtime relocations. Net: OF 879 -> 662 KB, EF 266 -> 214 KB. Verified byte-identical to lectio. The default build still needs only a compiler + libc; a CORPUS= rebuild now also needs gzip. lz.h removed. Claude-Session: https://claude.ai/code/session_01S1CD1u3tgSS4xNu6WHfp5a
