ci: build registry-index.json in-repo for dashboard real-time updates

Pair with the existing plugins-index.json path (which feeds the
daemon's signed install lane). registry-index.json mirrors the
dict-shaped payload the registry-worker's cron currently builds via
40+ GitHub Contents API calls — but built locally from the checked-out
tree by scripts/build-registry-index.mjs, so the worker only fetches
ONE file per category type (2 total: plugins + registry) on refresh.

Workflow now picks up content changes across all 8 category dirs
(was: plugins/ only) so dashboard updates land within seconds of a
push instead of waiting for the 02:00 UTC cron tick.

The dashboard's /api/registry endpoint reads kv_store('registry_data');
the worker's forced-refresh now writes that key with these bytes and
purges the Cache-API entry, so the next dashboard hit sees fresh
data instead of the 1h-cached previous payload.

Generated counts on first build: 11p 17h 32a 60s 44c 57pr 22w 33mcp.
