/**
 * Default mapping from IR `type.name` strings to Mongoose schema type strings.
 *
 * This table is the projection's sole interpreter of Manifest's open type
 * vocabulary for Mongoose. The projection knows what any given IR type name
 * means for Mongoose; nothing upstream carries Mongoose knowledge.
 *
 * Consumers can override per-property via `typeMappings`. Anything not in
 * this table and not overridden produces a hard diagnostic — no fallback,
 * no guessing. That is the contract.
 *
 * IMPORTANT: `'number'` is INTENTIONALLY ABSENT from this table.
 * Manifest's `number` is ambiguous between integers, real numbers, and
 * money. Silently mapping it to `Number` is exactly the class of silent
 * bug this project exists to prevent. Authors must pick a precise type:
 *   - `int` / `bigint` for counts and ids
 *   - `float` for measurements where rounding is acceptable
 *   - `money` / `decimal` for currency and other exact-decimal values
 * Bare `number` produces a hard MONGOOSE_AMBIGUOUS_NUMBER diagnostic.
