wayfinder: tighten blocking rule, update GH/GL templates

Concision pass on the blocking rule (fold the "wherever the tracker has
one" clause into the fallback sentence; drop restatements). Bring the
GitHub and GitLab issue-tracker templates up to the same standard: the
GitHub template now carries the native issue-dependencies recipe and
frontier query; the GitLab template names the native /blocked_by link
(Premium/Ultimate) with the body-convention fallback.

+Add a confirmation gate to **`grilling`**: the agent won't enact the plan until you confirm the shared understanding has been reached, turning the skill's existing "shared understanding" completion criterion into an explicit stop-gate. The `description` also recruits the pretrained **`grill`** leading word ("Grill the user relentlessly") to sharpen invocation, and the docs page is re-synced with the new gate behaviour.

+Sharpen Wayfinder's blocking rule to prefer the tracker's native dependency relationship, and update the GitHub and GitLab issue-tracker templates to match.
+
+Native blocking is essential rather than cosmetic: it renders the frontier visually in the tracker's own UI, so the human sees what's takeable at a glance without opening the map. `wayfinder`'s SKILL.md now states that preference and rationale; the GitHub template spells out the native issue-dependencies recipe (`gh api .../dependencies/blocked_by`, frontier query on `issue_dependencies_summary.blocked_by`), and the GitLab template names the native `/blocked_by` blocking link (Premium/Ultimate) with the body-convention fallback. Both keep the body fallback for trackers that lack native blocking.

+## What it does
+
+`research` answers a question by reading the sources that own the answer and leaving a cited Markdown file behind. It works only from **primary sources** — official docs, source code, specs, first-party APIs — never a secondary write-up of them, so what it saves is traceable back to something authoritative rather than a summary of a summary.
+
+## When to reach for it
+
+Type `/research`, or the agent reaches for it automatically when a task turns into reading legwork.
+
+Reach for it when the next step is *finding something out* — how an API behaves, what a spec actually says, whether a claim holds — and you'd rather not stall your own thread doing the reading. For sharpening a plan by interview instead of by reading, use [grilling](https://aihero.dev/skills-grilling); for exploring what to build with throwaway code, use [prototype](https://aihero.dev/skills-prototype).
+
+## Delegated legwork
+
+The defining move is that the reading runs as a **background agent**. You keep working; it goes off, follows each claim back to its primary source, and drops a single cited Markdown file into wherever the repo keeps such notes. Research is legwork you delegate, not thinking you outsource — you get back a document to react to, with its sources attached.
+
+## Where it fits
+
+A reach-for-it-anytime standalone that feeds the thinking skills: the file it produces is something to grill, plan, or design against, so it sits upstream of work like [grilling](https://aihero.dev/skills-grilling) and [to-prd](https://aihero.dev/skills-to-prd) rather than in the build chain. For the whole map, see [ask-matt](https://aihero.dev/skills-ask-matt).
