New SQLite high-score databases were previously created empty, so the first shared table had no original entries. Seed only database paths that did not exist before opening with the ten distributed demo scores, while leaving existing files and in-memory stores unchanged. Add coverage for both first creation and existing empty files, and document the behavior. Test Plan: - `just test-highscore-server` -- passed (8 tests) - `just clippy-highscore-server` -- passed - `cargo +nightly fmt --manifest-path highscore-server/Cargo.toml -- --check` -- passed - `git diff --cached --check` -- passed
