wayfinder: claim by assigning the ticket, not a label

A session now claims a ticket by assigning it to the dev driving the
map, rather than setting a `wayfinder:claimed` label. The assignee is
the claim; an open, unassigned ticket is unclaimed. Reads more naturally
in the tracker's own UI and frees the label vocabulary to
`wayfinder:<type>` alone.

Updates the GitHub and GitLab tracker-operations docs to the assignee
mechanism (`--add-assignee @me` / `--assignee @me`). The local-markdown
tracker keeps its `Status: claimed` line — a file store has no assignee.

+A session now **claims** a ticket by assigning it to the dev driving the map, rather than setting a `wayfinder:claimed` label. The assignee _is_ the claim — an open, unassigned ticket is unclaimed — which reads more naturally in GitHub's own UI and frees the label vocabulary to `wayfinder:<type>` alone. The *claim* leading word and its "first, before any work" rationale are unchanged; only the physical expression moved.

+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.
