fix(scripts): let issue.sh claim work on a write:issue-only token

`claim` is the one step the workflow requires before the first edit, and
it failed outright on a token scoped to the work it does: `me()` calls
`GET /user` purely to name the assignee, and that endpoint needs
read:user. So the documented process was blocked by its own tooling, and
the fallback was to do the assignment, the label and the comment by hand
— which is the half-made claim `claim` exists to prevent.

GITEA_USER short-circuits the lookup, so least privilege is enough. The
lookup stays as the fallback because it is right when the scope is there
and needs no setup. Failure is now actionable and says both remedies,
and it still happens before any of the three halves are mutated.

Closes #130

- * A hover affordance is gated on the device having hover.
