Make the nine-line compact Controller Handoff the default end-of-task
format; reserve the long Controller Handoff Summary for high-risk/complex
tasks (merge/tag/release, failed validation, blocked gates, secrets/prod,
complicated owner decisions, cross-repo state, or explicit owner request).
Compact form is for controller-LLM readability, safety confirmations are
never omitted, and PR bodies still carry full review detail.
Updates SKILL.md §K, llm-workflow-runbooks.md, and the start-issue /
review-pr templates. Documentation only.
Refs #101. Closes#108.
