* fix(export): escape Turtle/N-Triples string literals (fixes #1098) Add RDFSerializer._escape_turtle_literal and apply it to the semantica:text literal in serialize_to_turtle and the N-Triples text triple. Backslash, double quote, newline, CR, and tab are escaped per the RDF 1.1 Turtle STRING_LITERAL_QUOTE grammar, so entity text containing quotes or control characters no longer emits invalid Turtle/N-Triples. N-Triples previously escaped only quotes and newlines; now it also handles backslashes and tabs via the shared escaper. * fix(export): escape OWL-Time timestamp literals in Turtle output Addresses Qodo finding on #1148: the OWL-Time branch of serialize_to_turtle interpolated from_val/until_val directly into quoted literals. Apply _escape_turtle_literal there too so timestamps containing quotes, backslashes, or control characters cannot produce invalid Turtle. * chore: remove stray local files (AGENTS.md, evals superpowers docs) from PR branch ---------
