Author, scope, and decompose kitsoki proposals using the templates under docs/proposals/templates/. Use when the user wants to write a new proposal, pick the right template for a change, split a large/raw proposal into focused reviewable pieces, or keep a proposal's Status line / lifecycle honest. Covers the four focused kinds (story, runtime, tui, tracing), the epic-decomposition flow, the shared spine, and the trim-on-ship / delete-when-done lifecycle.
