Release v4.77.0

Added

• The MCP App and the VS Code event model board can switch from the board to a dependency map. The map shows modules as columns in suggested story order and features inside them, with other bounded contexts as outer nodes. Each edge is labelled with its kinds and the number of slice pairs behind it. By default it shows the dependencies that shape the story, and toggles add the others. Selecting an edge lists its slice pairs and the references behind them; in VS Code each reference opens its source. The map can be used with the keyboard and a screen reader. In the MCP App it follows the current or proposed model. (part of #415)
