Replace three uncoordinated logging systems (log.Printf, fmt.Fprintf
to stderr, fmt.Println warnings) with structured slog calls.
68 log calls migrated:
- log.Printf → slog.Error/Warn/Info (45 calls across 5 files)
- fmt.Fprintf(os.Stderr) → slog.Error (23 calls in main.go)
Kept unchanged:
- fmt.Println/Printf for CLI user output (version, banners, import results)
- engine.AddLog for TUI-visible ring buffer (monitoring events)
Store migration diagnostics demoted to slog.Debug (silent at default
info level). HTTP request logging now structured with method/path/
status/duration/ip attributes.
