- Added `MockHttpClient`, `MockHttpEngine`, and `MockWebSocketEngineFactory` to simulate network interactions.
- Extended `DebugOptions` for customizable engine injection.
- Updated `HttpCore` and `WebSocketTransport` to support mock engines in debug mode.

…ge handling

- Added `MockWebSocket` and `MockEvent` to capture WebSocket connection attempts, messages, and error scenarios.
- Added connection lifecycle events (`ConnectionEstablished`, `ConnectionRefused`, etc.) for enhanced testing.
- Updated `MockWebSocketEngineFactory` and related components to support event tracking and simulation.

- Added `Clock` interface and concrete implementations (`SystemClock` and `FakeClock`) for unified time management.
- Refactored classes (`Auth`, `Presence`, `Hosts`, `WebSocketTransport`, etc.) to use `Clock` instead of direct system calls.
- Enabled mockable time-based operations for improved testability.
- Updated `DebugOptions` to support custom clocks in debug mode.

…in tests

- Introduced a new skill for converting UTS pseudocode specs into runnable Kotlin tests.
- Included detailed translation rules for pseudocode to Kotlin, mock setup, and assertions.
- Added file templates and steps for compilation, testing, and handling deviations.
- Enhanced developer workflow for UTS test authoring.

…ssage decoding

- Added support for inspecting outgoing WebSocket frames (`MessageFromClient` events) in `MockWebSocket`.
- Enhanced `ClientOptionsBuilder` to set `useBinaryProtocol = false` by default for JSON text frame testing.
- Updated `ConnectionRecoveryTest` to assert on outgoing ATTACH messages.

…onnections

- Added `queryParams` field and `parseQueryString` utility for `PendingConnection` implementations.
- Updated `MockWebSocketEngineFactory` and `MockHttpEngine` to parse and pass query parameters.
- Enhanced connection recovery tests with assertions on query parameters.

- Added KDoc comments to `FakeClock`, `MockHttpClient`, and `MockWebSocket` explaining their purpose and usage.

… lifecycle management

- Introduced `ProxyManager` to manage the `uts-proxy` binary lifecycle, including downloading, verification, and process control.
- Added `ProxySession` for managing proxy sessions with rules, actions, event logging, and cleanup.
- Included KDoc documentation for clear usage guidelines in integration tests.
