6.0.0

Changed:
* Unknown, missing or empty modalities are now parsed as UNKNOWN

5.2.0

Added:
- Support for STADTRADELN modalities `CARGO_BIKE` (`CargoBike`) and `ECARGO_BIKE` (`ECargoBike`).
- Backwards-compatible read aliases for legacy modality identifiers: `Bike` → `BICYCLE`, `Other` → `UNKNOWN` (accepted on deserialization, never written).
- `Modality.forDatabaseIdentifier(String)` to resolve a modality from its persisted identifier (validates input and rejects null/empty/unknown values).
- `TrackBuilder` test coverage for the new modalities and legacy aliases.
- README documentation for the new modalities and the legacy read aliases.

Changed:
- `Modality` now uses a precomputed immutable lookup map for `forDatabaseIdentifier`, replacing the previous per-call `values()` allocation and linear scan.
- `TrackBuilder` class Javadoc normalised to US English (analyze/visualize).
