Federated STAC search.
Given a list of catalogs and a query::SearchQuery,
executor::SearchExecutor queries them concurrently (with retry,
pagination, and per-catalog timeouts), unifies item bodies via
unifier, and aggregates results in aggregator.
This crate is pure logic — it knows nothing about engine state or storage.
Use superstac_engine for the runtime that wires storage + search +
health together.
