- PreferencesDialog (Tools → Preferences, Ctrl+,): font family/size,
word wrap, default page size, query timeout, max history, auto-commit;
font changes apply live to all open editors via apply_settings() cascade
- CodeEditor and TableViewer now read initial values from settings singleton
- SQL formatter (≡ Format button): uses sqlparse to reindent and uppercase
keywords; gracefully prompts to install sqlparse if missing
- Table viewer context menu: "Filter by this value" (populates WHERE and
reloads), "Copy row as SQL INSERT" (ready-to-paste INSERT statements),
renamed "Copy row" → "Copy row as TSV" for clarity
