Two introspection endpoints for OpenBrain:
- GET /v1/brain/tags — ES terms aggregation over tags.keyword, returns
{tag: count} pairs for UI filter chips
- GET /v1/brain/scopes — composite aggregation over {org, project},
returns the scope hierarchy present in the index
Sits under the existing brain.read-auth group in Routes/api.php. New
BrainService helpers for aggregation shape; reuses the elasticSearch
HTTP path added in #59.
Pest coverage with Http::fake for ES.
