dsh-task-hub: Read to-dos from TAPD/Zentao into DSH and assign branches to Agents

dsh-task-hub is a DSH workflow plugin maintained by handsomeboy65. The sidebar lists TAPD requirements or Zentao tasks where the assignee is the current user. After selecting a workspace and manually entering the full branch name, the task can be dispatched. The plugin uses git worktree/checkout to create branches, creates a DSH session, populates the input draft with the requirement body and attachments, and redirects without auto-submission. The two sources are mutually exclusive via tabs. Configuration is stored in `settings.json`, and credentials are handled via DSH credentials. It is suitable for scenarios where developers decide branch names and do not want to write back to the source system. The plugin runs with the permissions of the current DSH process; please review the source code and MIT license before installation.
