Ekaterina Broslavskaya bb94246d2b feat(core): steward violation detection and emergency criteria proposal (#52) ...

* feat: implement emergency criteria proposals and violation detection

- Introduced support for emergency criteria proposals in the consensus mechanism, allowing for the detection of steward violations during commit validation.
- Enhanced the `GroupUpdateRequest` to include an `EmergencyCriteriaProposal` message type, encapsulating violation evidence.
- Implemented logic to handle violations, including broken commits and censorship inactivity, with appropriate evidence reporting.
- Updated the `handle_consensus_event` function to manage emergency proposals correctly, ensuring they do not produce MLS operations.
- Refactored related components to improve clarity and maintainability, including the addition of a `ProposalPriority` enum to manage proposal handling based on urgency.
- Enhanced tests to cover new functionality and ensure robustness in violation detection and emergency proposal processing.

* feat(api): add steward_identity handling in batch proposals

* fix: fix lint error

* feat(core): enhance group configuration with quarantine policy and commit timeout

- Introduced `QuarantinePolicy` to manage unsolicited batch behavior, including maximum items and epoch age.
- Updated `GroupConfig` to include `commit_timeout` and `quarantine_policy`, with default values.
- Refactored group handle creation methods to accept custom policies for group management.
- Enhanced `apply_consensus_result` to validate consensus outcomes against the group's state.
- Added display helpers for converting group update requests to user-friendly formats.
- Improved documentation and tests to cover new functionalities and ensure robustness.

* refactor(app): reorganize group state management and enhance freeze handling

- Updated the group state machine to include new states: Freezing, Selection, and Reelection, improving clarity in state transitions.
- Refactored the handling of commit timeouts, replacing it with freeze timeout logic to streamline candidate selection.
- Introduced new methods for checking freeze timeouts and managing proposals during the freeze phase.
- Enhanced the `GroupConfig` to support freeze duration and subset candidate handling.
- Added display helpers for converting group update requests to user-friendly formats.
- Improved documentation and tests to cover new functionalities and ensure robustness.

* refactor(app): reorganize message handling and introduce message type system

- Refactored message handling in the app layer to improve clarity and maintainability.
- Introduced a new `message_type` module to define app-layer message type labels for better consistency and type safety.
- Updated various components to utilize the new message type system, enhancing the handling of `GroupUpdateRequest` and related messages.
- Added helper methods for converting violation evidence into user-friendly formats for display.
- Improved documentation and tests to cover new functionalities and ensure robustness.

* refactor(app): introduce UserError for app layer error handling and update event handler callbacks

- Added a new `UserError` type to encapsulate application-specific errors, improving error handling across the app layer.
- Refactored event handler methods in `GroupEventHandler` to return `CallbackError` instead of `CoreError`, enhancing clarity in error reporting.
- Updated various components to utilize the new error handling structure, ensuring consistent error management throughout the application.
- Improved documentation and tests to cover new error handling functionalities and ensure robustness.

* refactor(ui): enhance consensus panel layout and state management

- Adjusted the CSS for the consensus panel to improve spacing and layout, specifically reducing the margin for status rows.
- Introduced new state context elements in the UI to display approved proposals and member counts based on the current group state.
- Updated the Rust code to normalize address formatting and enhance event handling for group state changes, ensuring accurate updates during transitions.
- Improved the handling of group state display, including new states and their corresponding UI representations.
- Enhanced documentation and tests to cover the new UI features and ensure robustness.
