/**
|
|
* React Query key factory for the search domain.
|
|
*
|
|
* **The filter object IS the query key** (phase §5, the caching contract). `results(filters)` keys on a
|
|
* **canonical** serialization of the full filter object — a stable key order with every *absent* optional
|
|
* filter omitted (never carried as `undefined`). Two filter sets that are semantically equal therefore
|
|
* produce the identical key, so changing a filter and **reverting** to a previous set is a cache hit with
|
|
* zero network calls (React Query hashes query keys deterministically; canonicalizing here makes the
|
|
* intent explicit and keeps the URL/query-param serialization aligned with the cache key).
