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.

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.
Replaced `origin/develop/3.5.0` with `origin/main` to align the workflow with the updated branch structure. This ensures compatibility and avoids referencing deprecated branches.
Updated the base version from 3.5.0 to 3.6.0 in the workflow configuration. Also modified the branch check to look for 'origin/main' instead of 'origin/develop/3.5.0' to align with the main branch structure.
