The tengu_melodic_wolf flag behind CLAUDE_CODE_HANDBACK_PROVENANCE now defaults to true instead of false

What The internal flag tengu_melodic_wolf, which controls the CLAUDE_CODE_HANDBACK_PROVENANCE setting, now defaults to true instead of false when not otherwise overridden.

Why Handback provenance is now on by default for everyone, rather than requiring users to opt in explicitly.
