Querly v1.4.1

🔧 What is new in v1.4.1

Refactoring & Architecture

• DatabaseDriver stripped to minimal shared surface — removed wrongDriver stubs from MySQL/Postgres/SQLite drivers. Schema/data methods stay concrete per-engine.
• CoreModels extracted — DBColumn, TableRow, StatementKind moved out of Models.swift into pure-Foundation module, enabling SPM compilation and unit testing.
• SQLSafety extracted — read-only mode classification, no-WHERE guard, DML target extraction moved from ConnectionStore into focused, tested module.
• SimpleCSV parser extracted — inline CSV parser moved from ConnectionStore to its own file with unit tests.
• ModelPresentation separated — color/icon mappings for models moved to dedicated AppKit-dependent layer (SRP).
• FilterClauseBuilder extracted — filter WHERE clause generation moved out of TableDataView.
• DBErrorClassifier extracted — error classification moved out of ConnectionStore.
• Connection import parsers extracted — parsers moved into QuerlyCore test target.
• Value-list filter clause builder extracted — separate module for filter chip logic.

Fixes

• SQL formatter: no space after . in qualified names (e.g. t.a)
• SQL formatter: space-before on compound JOIN keywords (LEFT OUTER JOIN)
• SPM test target expanded: SQLImportHelper, AWSRDSAuth, CoreModels, ExportHelpers, SQLSafety, SimpleCSV

Testing

• 162 → 176 tests — added test suites for: AWS RDS auth (SigV4), SQL formatter, SQL import helper, CoreModels, export helpers, SQL safety, SimpleCSV parser
• Driver integration test scaffolding — initial test plan for MySQL/Postgres/SQLite integration tests
