Research direction

Start with the README feature matrix and the functions under xrspatial/hydro/. Review the unresolved decisions in #2930, then run the indicated /deep-sweep xrspatial/hydro checks. Done means the public surface, dark-corner decisions, accuracy, security, performance, API consistency, and examples are cleared for the 1.0.0 checklist.
