/**
 * Insight list vocabulary — the filter and ordering tokens `GET /api/insights`
 * accepts, minted once so every consumer spells them the same way.
 *
 * Owner today: the webapp (`webapp/app/lib/insights/insights.ts` —
 * `TAB_VALUES`, `INSIGHT_CATEGORIES`, `INSIGHT_SEVERITIES`, `SORT_VALUES`).
 * The MCP's `list_insights` tool re-typed all four by hand and advertised
 * them on its wire surface, so a token added or renamed in the webapp left
 * the tool silently offering a filter the route rejects. The MCP now derives
 * from here, and the route's 400-on-unknown gate is what keeps the two honest
 * while the webapp still carries its own copies.
 *
 * Client-safe (no node built-ins): exported from the root barrel and as the
 * `@fjall/util/insights/vocabulary` subpath so browser code can take it
 * without the root barrel.
