Updated the SignalBookmarkQueueWorker to implement INotificationHandler for WorkflowInstanceSaved. This ensures that workflow instance save events now trigger the bookmark queue worker, improving event handling consistency.
* Update comment to clarify bookmark and workflow instance check
Expanded the comment to explain that the queue item is stored not only when a bookmark is missing but also when the associated workflow instance is not yet in the database. This improves clarity for future maintainers regarding queuing conditions.
This commit cleans up Program.cs by removing several unused using directives. The removal helps improve code readability and eliminates unnecessary references, ensuring a leaner and more maintainable codebase.
Deleted unused custom activity classes, message types, and related registrations from the codebase. Also cleaned up surplus library references and configurations from Program.cs to streamline and simplify the project.

Removed obsolete `JoinKind` enum and `IJoinHintProvider` interface, replacing them with the new `JoinMode` concept. Simplified flowchart logic by consolidating flow graph handling and refining activity execution extensions. Updated `FlowJoin` to recommend property-based configuration over explicit usage.
* Avoid invalid test execution when token flow is enabled.
The added check prevents the test from running when `Flowchart.UseTokenFlow` is enabled, as this scenario is incompatible. This ensures test reliability and avoids unnecessary execution.
* Refactor token-based logic in Flowchart activity.
Simplified token handling and introduced clearer logic for WaitAny and WaitAll joins. Improved efficiency by reducing redundant checks and streamlining activity scheduling. This ensures better maintainability and functionality in complex workflows.
* Refactor Token logic into its own model class
Moved the Token logic out of the Flowchart partial class to a standalone `Token` model for better modularity and clarity. Adjusted token consumption behavior to mutate the token in place rather than replacing it.
* Fix ancestor cancellation logic in Flowchart activities
Pass the correct activity to CancelInboundAncestorsAsync to ensure accurate ancestor determination and cancellation. Added validation to confirm the activity context is a flowchart to prevent invalid operations. These changes improve the reliability of flow control in workflows.

The WaitAny guard logic and associated key have been commented out and effectively disabled. This cleanup simplifies the code, removing unnecessary operations that were no longer in use. The change ensures better maintainability and focuses on the core functionality.
* Add `MergeMode` enum and refactor flowchart merging logic
Introduced a `MergeMode` enum to define strategies for handling multiple inbound execution paths. Updated flowchart logic to replace the previous `FlowJoinMode` with `MergeMode`, and refactored related extensions to accommodate the new enum. This enhances clarity and flexibility in workflow merging behaviors.
* Mark `FlowJoin` obsolete and enhance merge mode handling
Added the `[Obsolete]` attribute to the `FlowJoin` activity and deprecated properties to encourage using `MergeMode`. Replaced synchronous `GetMergeMode` with an asynchronous `GetMergeModeAsync` to handle legacy `FlowJoin` mappings dynamically. Other minor changes include simplifying variable initialization in `WorkflowExecutionContext`.
* Mark FlowJoin activity as obsolete
The FlowJoin activity is now marked obsolete since all activities support the MergeMode property, eliminating the need for explicit join steps. This change includes an annotation update to clearly communicate its deprecated status.
* Refactor `OnActivityCanceledAsync` method location
Moved the `OnActivityCanceledAsync` method from the `Flowchart.Counters` file to the main `Flowchart` file for improved organization and readability. This ensures the method aligns better with its primary logic and related functionality.
* Refactor flowchart logic to improve cancellation handling
Refactored `OnActivityCanceledAsync` to handle token-based flow and legacy flow separately for better clarity and maintainability. Moved `CompleteIfNoPendingWorkAsync` to a single shared location and updated pending work checks to include unconsumed tokens and faulted activities. Simplified redundant logic and ensured consistency across methods.
* Remove consumed tokens after activity completion
This update ensures that consumed tokens pointing to the completed activity are purged from the token list. This helps maintain a clean state and prevents unnecessary token accumulation during workflow processing.
* Add support for blocking tokens in flowchart activities.
Introduced a `Blocked` property to the `Token` model to prevent scheduling activities prematurely in certain merge modes. Updated token processing logic to handle blocked tokens effectively and ensure proper scheduling or consumption. Simplified token management by removing redundant methods and cleaning up consumed tokens appropriately.

* Remove JoinMode-related methods from ActivityExtensions
The GetJoinMode and SetJoinMode methods were removed as they are no longer needed. This cleanup reduces unused code and improves maintainability of the ActivityExtensions class.
* Remove unused JoinMode enum
The JoinMode enum was determined to be unnecessary and has been deleted to clean up the codebase. This helps reduce redundancy and improve maintainability.
* Remove unused LoopbackDetector class from Flowchart module
The LoopbackDetector class was removed because it is no longer used in the codebase. Its functionality appears to be obsolete or unnecessary for the current requirements of the Flowchart module.
* Update `UseTokenFlow` to be configurable
Made `UseTokenFlow` a static field to allow external configuration. This enables users to switch between the token flow and the old counter-based model as needed. Updated documentation accordingly.
Updated package references to their latest versions in `Directory.Packages.props`, ensuring compatibility and access to the latest features. Enabled `MongoDB.Driver.Core.Extensions.DiagnosticSources` in `Elsa.MongoDb.csproj` and cleaned up unused ElsaStudio version property in `Directory.Build.props`.

* Align .gitignore file with consistent formatting
Standardized comments in the .gitignore file by adding missing spaces and capitalizing as needed. Updated the `/docker/data/` entry to `/docker/azurite-data/` for clarity.
* Fix incorrect selection of activity execution context
Replaced `LastOrDefault` with `FirstOrDefault` to ensure the correct activity execution context is retrieved when handling errors. This change resolves potential inaccuracies in identifying the faulted activity node.
* Exclude docker-compose-datadog.yml from solution file.
