Add profile-scoped feedback endpoint

New POST /api/profiles/{name}/feedback accepts explicit vibe text and
records feedback against a named profile. GET history endpoint added too.
Scoring now filters feedback by profile_name for profile-aware playlists.
Migration 005 adds profile_name column and makes playlist_id nullable.
