feat(skills)!: add kvb-create-requirement and kvb-think-brainstorm, rename kvb-create-feature to kvb-think-gaps

kvb-create-requirement asks for the context, runs kvb-think-listen and kvb-think-brainstorm, then drafts one requirement with a user story, operator-confirmed decisions, a Mermaid approach flowchart with emoji phases, a test loop and an operator feedback checkpoint per stage, checkbox acceptance criteria grouped by area, and a Tests group with unit, integration and e2e (n/a with a reason). It writes only on the operator's Write it and stops with an offer to hand over to kvb-create-plan. kvb-think-brainstorm generates options through seven fixed lenses, scores them on value, effort and risk, and hands the best two or three over. kvb-create-feature becomes kvb-think-gaps: it still finds and ranks missing work but delegates every pick to kvb-create-requirement, so the requirement template lives in one place. Operator order 2026-11-03.

BREAKING CHANGE: /kvb-create-feature is now /kvb-think-gaps.
