- #66752: \[Bug\]: config.set may overwrite the full config after YAML parse failure and strips round-trip metadata

- PR #71809: fix(tui_gateway): stop TUI config toggles from wiping config.yaml on invalid YAML

These members all concern config.set or TUI config toggles potentially overwriting or wiping the full config when YAML parsing fails. One is a bug report that also mentions loss of round-trip metadata, and two are fix proposals aiming to fail closed on invalid YAML (one also mentions preserving comments).
