// Wraps the Zig usage core for native hosts. Build the library first:
//   zig build                        (repo root, produces zig-out/lib/libusage.a)
// then:
//   swift build --package-path swift
//
// The core does no I/O: it builds the requests and parses the responses, and UsageDriver feeds it
// through URLSession. That is the whole point of the split — TLS, proxies and HTTP/2 stay with the
// host, and the rules stay in one place shared with the CLI.
//
// The path to libusage.a is absolute because this package is also consumed as a dependency: a
// relative path would be resolved against whoever is building, not against this directory.
