 * Strategy (see docs/internal/proposals/2026-07-14-convex-computed-properties.md):
 *   - `helpers` (default): emit convex/computed.ts of pure functions per entity.
 *   - `inline`: materialize self-only computeds into get/list returns.
 *
 * Unresolved expressions always emit CONVEX_UNRESOLVED_COMPUTED — never silent drop.
 * Multi-hop aggregates also emit an async hydrate helper that preloads every
 * relationship depth onto the document before the sync compute helper runs.
