+Parses simple line-based key/value text into a `StringMap`.
+
+Each non-empty line is split on the first `separator`. Lines without the separator are kept with an empty value.
+
+Example:
+
+```uce
+StringMap cfg = split_kv("host = localhost\nport = 8080");
+// cfg["host"] == "localhost"
+// cfg["port"] == "8080"
+```
+
+This is useful for small config files, metadata blocks, and tests that need predictable key/value parsing.
