0.30.0

• Added deserialize_any_with_raw_strings() for Serde-based format adapters
  to validate MMDB strings while constructing another runtime's native string
  type, avoiding duplicate UTF-8 validation without unsafe Rust. Adapters
  remain responsible for strict UTF-8 validation.
• Fixed network iteration on cyclic or over-deep corrupt search trees so it
  returns an error instead of looping indefinitely.
• Fixed decode_path() error rendering for extreme negative indexes and
  reduced path traversal header parsing.
• Removed decoder logging checks from hot deserialization paths.
• Fixed verify() to validate shared data-section pointer targets once, reject
  pointer cycles, invalid scalar encodings, and impossible container sizes.
