v0.2.9

Changed

• Calmer startup when on-device models aren't present. A semantic-capable build (the default release binary) running before pull-models now logs a calm NOTE and serves lexical BM25/FTS, instead of an ERROR plus a desktop alarm. Lexical-only is a supported default; the loud ERROR + alarm + refuse-to-serve is now reserved for MEMKEEPER_REQUIRE_SEMANTIC=1 (fail-closed).
