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.

 `grilling` is the relentless interview that stress-tests a plan or design before you build it. It walks down the design tree branch by branch, resolving the dependencies between decisions one at a time until you and the agent share the same understanding.
 
-It asks **one question at a time** and waits for your answer before the next — never a bulk list, which is bewildering. Each question comes with the agent's own recommended answer, and any question the codebase can settle it explores instead of asking you.
