ci(hypatia-scan): grant actions:read so the reusable can start (the real fix)

[hyperpolymath]

Confirming the #39 repin: it did not fully fix hypatia-scan — and this is the missing half.

After #39 repinned the reusable to a resolvable SHA (8e6ba7d), eclexia's hypatia-scan stopped failing with 0 jobs and instead began failing as startup_failure (runs 23f5945a, 9d8e05f on main). Root cause: the standards hypatia-scan-reusable.yml declares permissions: including actions: read, but the caller's permissions: block listed only contents/security-events/pull-requests. Specifying any permissions block pins every unlisted scope to none, so the reusable's actions: read request exceeds the grant → the run dies at startup before scheduling jobs.

Fix: add actions: read to the caller. Combined with the resolvable pin from #39, the reusable's full permission contract is now satisfied.

This PR is the canary. Its own hypatia-scan run (on this PR) is the empirical test — if it executes real jobs / goes green, the diagnosis is confirmed and the identical fix applies estate-wide to the other reusable-wrapper repos (Axiom.jl, nextgen-languages, nextgen-typing — all currently 0-jobs-failing at three different stale pins, so each needs repin + actions: read). The 4 inline-scan repos (echo-types, Axiology, Cliodynamics, Cliometrics) don't call the reusable and are unaffected.
