docs(core): replace conformance catalog with S1 v1.9 examples Rewrite Catalogo-conformance-Core.md, replacing the Triad-Core conformance case table (expected outputs and exit codes per case) with S1 v1.9 bootstrap examples written in Triad: inline environment creation and lookup, parser keyword recognition for "if" and "end", and a sequential program evaluator supporting assignment and println. This aligns the document with the S0→S4 bootstrap plan (S1: Triad-Core interpreter in Triad-Core) rather than JS interpreter conformance results.
