tracker-backed evidence bridge for skill progress tracking — VibeSkill MCP

Built the tracker-backed bridge layer used by VibeSkill to access structured work history. This integration supplies project and journal records from the tracker in a format that can later be normalized into evidence, mapped onto skills, and reviewed against other sources like GitHub. Its role is to provide a clean project-level source of truth for tracked work so VibeSkill can reason about progress using real records instead of manual claims.
