+- Performance improvement: Skipped UTF-8 validation for map keys during
+  deserialization. This significantly speeds up full record decoding by
+  treating keys as raw bytes when matching against struct fields.
+- Performance improvement: Optimized tree traversal by reducing bounds checks
+  during node reading.
