refactor(content): rename mood vocabulary to match voice guide (D-035 Sprint 14 amendment)

Schema and Rust Mood enum renamed for author-friendly vocabulary:
fond→warm, comfortable→content, worried→anxious, concerned→frustrated.
Dropped: analytical (merged into focused), conflicted (modeled as
suspicious+warm collision). Added: hostile. Final 8 moods: anxious,
frustrated, content, suspicious, warm, hostile, relieved, focused.
Neutral = untagged. Resolves Gestalt's blocking issue on #121.
