--- "mattpocock-skills": minor --- Rename the **`decision-mapping`** skill to **`wayfinder`**, invoked as `/wayfinder`. "Decision map" was jargony and inaccurate — only one of the skill's four ticket types (Grilling) is actually a decision. The skill is reframed around the **Wayfinder**: you chart a route through a foggy problem, resolving investigation tickets one at a time until the way to the goal is clear. This makes one coherent leading-word frame (fog of war / frontier / the map) instead of mixing an invented term on top of it. Also a pruning pass: unified `node`→`ticket`, bound "the frontier" to the unblocked tickets, dropped the duplicated "one question at a time" (owned by `/grilling`), and trimmed intro no-ops.
