Replace the stale triage label vocabulary with the org label taxonomy

The five labels this doc named (needs-triage, needs-info, ready-for-human,
wontfix) do not exist in the tracker. The org has an 18-label taxonomy
(Kind/*, Priority/*, Status/*, Reviewed/*, Compat/Breaking) that agents never
used, because nothing pointed at it. Kind/Bug had been applied twice, ever.

Document the real set, make one Kind/* label required on every issue and PR,
and map the outside-skill vocabulary onto labels that exist.
