* perf(routes): batch cross-IATA and hash route search (#216)
One search fired a /routes/cross request per IATA pair (138k on 2026-10-08). Route search now takes an optional iatas list and runs a fixed number of index-backed queries. /info advertises built-in minimum client versions.
* chore: bump version to 2.0.4
any route observer where all hops are high confidence
are now stored and available at /routes
you can also search for a src dest route and it will
return any recored route subset that can link the src
and dest hash
