DDS Fuzz: Add Rollback

[anthony-murphy]

This pull request introduces a new "rollback" operation to the DDS fuzz testing framework, along with supporting changes to the mock runtime utilities. The most notable updates include the addition of the Rollback interface, modifications to the operation generation logic, and enhancements to the mock container runtime to support manual flush mode for rollback operations.

Changes to DDS Fuzz Testing Framework:

• Added a new Rollback operation type, including its interface (Rollback) and integration into the HarnessOperation union type. This allows the framework to simulate rollback scenarios during fuzz testing. [1] [2]
• Introduced a rollbackProbability option in DDSFuzzSuiteOptions and set a default value of 0.01 in defaultDDSFuzzSuiteOptions. This determines the likelihood of triggering a rollback during fuzz testing. [1] [2]
• Added a mixinRollback function to extend the fuzz testing model with rollback functionality. This includes logic for generating rollback operations and applying them during state transitions.
• Updated the getFullModel function to include the rollback mixin in the composition of the fuzz testing model.

Changes to Mock Runtime Utilities:

• Enhanced the MockContainerRuntime class by adding a runWithManualFlush method. This enables manual control over flush mode, allowing operations like rollback to be executed in a controlled environment.
• Modified the submit method in MockContainerRuntime to respect manual flush mode when active, ensuring rollback operations are handled correctly.
