mindforge-plant-seedlisted

<objective> Capture an idea that's too big for now but should surface automatically when the right milestone arrives. Seeds solve context rot: instead of a one-liner in Deferred that nobody reads, a seed preserves the full WHY, WHEN to surface, and breadcrumbs to details. Creates: .planning/seeds/SEED-NNN-slug.md Consumed by: /mindforge-new-milestone (scans seeds and presents matches) </objective> <execution_context> @.agent/workflows/mindforge-plant-seed.md </execution_context> <process> Execute the plant-seed workflow from @.agent/workflows/mindforge-plant-seed.md end-to-end. </process>
