Added the post-utils skill, which scaffolds section drafts and promotes them to published via a Haiku subagent.
Give the blog post file lifecycle a repeatable, section-aware convention: scaffold a draft into <section>/_drafts/ with a complete Jekyll front-matter block, and promote it into <section>/_posts/ with a dated filename via git mv — replacing the manual, non-section-aware rake post:create. Part of executing plan-003.
