Alex Howells e56304b7f5 refactor(cmd): replace fmt.Printf with zerolog in supervisor (#1302) ...

The supervisor process in cmd/main.go used fmt.Printf for
operational messages (error dump handling, version mismatch
fatal), while the KVM application uses zerolog throughout.
The plain-text output mixed with zerolog-formatted output on
the same stdout stream, breaking log parsability for anyone
collecting logs via journald or similar.

Replace the five fmt.Printf calls in createErrorDump() and
the version mismatch fatal in main() with a supervisorLogger
using the existing logging.GetSubsystemLogger infrastructure.
Add "supervisor" to subsystemDefaultLevels at InfoLevel so the
"error dump saved" message is not suppressed by the default
ErrorLevel threshold.

Intentionally left unchanged:
- Version flag output (fmt.Println) — CLI output, not logging
- Crash info written to log file (fmt.Fprintf) — file I/O
- fmt.Sprintf calls — string formatting, not logging
- setProcTitle — process title, not logging
