bug fixes

• fixed :ensure DDL failing on existing relations — replaced :ensure with :create for all schema creation statements. :ensure in CozoDB v0.7 is a transactional row assertion, not idempotent DDL, causing relation_not_found errors on first run and stored_relation_conflict on subsequent runs.
• added _tryQuery helper for idempotent schema creation — catches stored_relation_conflict and index_already_exists errors gracefully, allowing safe re-initialization without crashes.
• fixed string escaping in CozoScript queries — added proper _escapeCozoString() in cozo_graph.dart and cozo_vector_search.dart that escapes backslashes, double quotes, newlines, carriage returns, and tabs. previously, only double quotes were escaped, causing pest::parse errors when content contained multi-line text or special characters.
• updated example app — migrated all 7 :ensure calls to :create with _tryQuery wrapper in db_service.dart.

internal

• schema creation is now fully idempotent — safe to call on every app startup without error.
