h-explore

Generates 3–5 genuinely distinct candidate solution variants for a framed problem — each variant differs in KIND (not just degree), carries an explicit weakest-link so weak options surface before implementation, and optionally marks stepping-stones that open future search space. Make sure to use this skill whenever the user asks "what are our options", "how could we do X", "brainstorm approaches", "give me alternatives", "different ways to X", "what variants should we consider", "what else could we try", or whenever they are about to commit to one approach without having generated alternatives. Also use when a problem is framed but only one solution sits on the table. NOT for comparing existing options head-to-head (use h-compare). NOT for hypothesis testing on a failure (use h-diagnose).
