-- Team template categorization for wizard filtering.
--
-- Wizard step 3 shows "Research teams" + "Development teams" panels.
-- Filtering by category lets each panel show only relevant templates
-- rather than the operator wading through the whole catalog.
--
-- Categories:
--   research    — codebase deep-dive, papers ingest, insight, continuous
--   development — implementation teams (backend, frontend, mobile, gpu, ...)
--   security    — reserved for future security-hardening teams
--   ops         — reserved for future infra/deploy teams
--
-- Existing templates default to 'development' — they were all coding
-- teams before this slice added research templates.
