Fixes #120. Part of #54. - Wrap statements and metadata so Statement.getConnection() and DatabaseMetaData.getConnection() return the same connection proxy, and closing through either releases the namespace once. - Track the underlying connections per namespace. stop() now fails when a namespace still has an open connection, and reports namespaces whose cleanup failed instead of clearing them silently. Reconcile an escaped raw connection closed through unwrap before declaring a leak. - Treat SQLite file: memory URIs (file::memory:, ?mode=memory) as per-connection namespaces and include the query string in the file namespace identity, so options isolate databases instead of being ignored. - Add XerialHarnessTest: wrapped identity, release-once, stop failure on a leaked connection, swallowed cleanup failure reporting, file memory isolation, and query-string isolation. No production driver code changed. The JSON1Test and CachedRowSetTest connection closes stay in the vendored copies: they leak top-level connections, which the stricter stop() must reject, not connections obtained through statements or metadata. Contract: Hrana 3 is the transport and value source; java.sql defines the connection and wrapper surface; xerial remains the conformance reference. The query string is namespace identity only because sqld has no URL pragma surface. Evidence: - Red: ./mvnw -pl libsql-conformance -am test-compile failed; the harness test could not compile against the old driver/server APIs. - Green: ./mvnw -pl libsql-conformance -am verify -> 123 tests, 0 failures, 1 skipped. - Green: ./mvnw -pl libsql-conformance -am -Pxerial-control verify -> 100 tests, 0 failures, 1 skipped. - Green: XerialHarnessTest -> 8 tests, 0 failures. - Green: ./mvnw -pl libsql-jdbc test -> 235 tests, 0 failures. - Green: ./mvnw test, ./mvnw -pl libsql-jdbc -am package -DskipTests, ./mvnw spotless:check, ./tools/export-upstream --verify.
