GEO Retrofit Benchmark (v1.0.0)

Additive answer-first + FAQ retrofit engine and structural GEO/AEO detection gate that took a real bilingual (IT+EN) content corpus of 194 articles from 741 structural GEO/AEO findings to 0, with a synthetic before/after fixture pair and the exact command to reproduce the transform end to end (`node --test test/reproduce.test.mjs`). The 194-article corpus itself is not redistributed; the transform and gate logic that produced the result is shipped in full and is mechanically verifiable against the fixture pair. Code: MIT. Contents of `fixtures/`: CC-BY-4.0.
