Summary

• Add portable connection importers and a Linux review dialog for connections, groups, passwords, TLS, SSH and saved queries. Match macOS duplicate choices, recheck the library before saving, preserve held names, and store passwords in the keyring.
• Fix Swift importer parsing, file limits, key passphrases, KeePass decoding, URLs and TLS defaults, including Beekeeper TLS. Wait for query history before importing saved queries.
• Keep unsupported engines visible but unselectable. Unknown TLS modes start unchecked with a note. Core ADR 0008 records the API; Windows importer FFI is a later item.
• Fix Windows editor-readiness and Linux concurrent-connection test races. Existing behavior assertions remain unchanged. Packaging and workflows are unchanged for the shared RPM disk defect.

Test plan

• Local Mac verification passes: core importer/storage tests, Linux build/lint/localization and 2,740 app tests, Windows solution build and 184 tests. The final concurrency fix also passes 148 core session tests, all 18 GTK session-window tests, formatting and workspace lint with/without defaults.
• Swift importer and package tests, lint and localization passed before the main merge. Windows x64 and Arm64 UI CI passes on the current commit; reopened-query screenshots were checked in both themes. Remaining CI is being watched.
• Intentional test changes: testCollect_sslEnabledEmptyModeDefaultsToPreferred becomes testCollect_sslEnabledEmptyModeIsUnread; testCollect_noSSLForTLSModePastDriverVocabulary becomes testCollect_unreadTLSModePastDriverVocabulary; testCollect_noSSLWhenDisabled becomes testCollect_sslOffOverTCPPrefersTLS.
• Screenshots use the built Linux app under Xvfb with seeded app folders.
