to-issues: prefer native sub-issues; reference /prototype code explicitly

Two minimal edits to the to-issues skill:

- The "What to build" template now points explicitly at the `/prototype`
  skill's code as the source of an inlined decision snippet, rather than
  gesturing at "a prototype".
- Publishing now prefers the tracker's native sub-issues (parent → slice)
  and native blocking edges (Blocked by) where supported — mechanics
  already documented in the issue-tracker doc — keeping the `## Parent`
  and `## Blocked by` body sections as the fallback.

+Give **`wayfinder`** a first-class notion of **out of scope**, separate from fog.
+
+Fog and out-of-scope were conflated under one `## Fog` map section, gated by different things: fog by *knowledge* (can't specify it yet — in scope, unripe, graduates as the frontier advances), out-of-scope by *scope* (beyond the destination — never graduates). Cramming both under "Fog" made out-of-scope work read as takeable frontier (an unblocked, unclaimed item is indistinguishable from a live ticket).
+
+Now the map body has two plainly-named sections — **`## Not yet specified`** and **`## Out of scope`** — and the skill's prose splits to match: the **Fog of war** section teaches only the not-yet-specified bucket and keeps the two-way *fog-or-ticket* sharpness test, while a new **Out of scope** section owns the scope axis (beyond the destination, closed not graduating, returns only as a fresh effort if the destination is redrawn). Charting and working-the-map now rule a beyond-destination ticket out of scope — close it, one line in *Out of scope* — rather than leaving it on the frontier or logging it in *Decisions so far*.
+
+The **fog of war** leading word is retained: it names the concept and drives the graduate-the-fog behavior in the prose; only the human-facing map headings go to plain language.

+Sharpen **`wayfinder`**'s top-level purpose around **destination** as the leading word: wayfinding finds the *way* to a destination, it doesn't charge at building it.
+
+The opening now states that the destination varies per effort — a spec to hand off and iterate, a decision to lock before planning, or a change made in place like a data-structure migration — and that naming it is the first act of charting, because it shapes every ticket. The map body gains a `## Destination` field that every session orients to before choosing a ticket, and triage's first step now pins the destination before any ticket exists. The stray `goal` mentions in the description and Fog section are unified onto `destination`.

+**Not yet specified** excludes what's already decided (Decisions so far), what's already a live ticket, and what's out of scope (the next section).
+
+## Out of scope
+
+Fog only ever gathers _toward_ the destination. The destination fixes the scope, so work beyond it is **out of scope** — it isn't fog, and it doesn't belong in **Not yet specified**. It gets its own **Out of scope** section on the map: work you've consciously ruled out of _this_ effort. Scope, not sharpness, lands it here.
+
+Out-of-scope work never graduates — the frontier stops at the destination — so it returns only if the destination is redrawn, and then as a fresh effort, not a resumption.
+
+Ruling something out of scope is a scoping act, not a step on the route. When a ticket that already exists turns out to sit past the destination — mis-scoped in while charting, or exposed by a resolution — **close it** (a closed ticket is unambiguously off the frontier) and leave one line in the **Out of scope** section: the gist plus why it's out of scope, linking the closed ticket. It stays out of **Decisions so far**, which records the route actually walked — a scope boundary isn't a step on it.
