task-add
File a new taskwarrior task with blueprint linkage (bpid/bpdoc/bpms) and, when a GitHub remote is present, optional issue linkage via ghid. Checks for duplicates by bpid, offers to pre-fill from an existing GitHub issue, or offers to create a new issue. Use when adding a coordination task for multi-agent work, linking a blueprint WO to an actionable queue entry, or mirroring a GitHub issue into the local task queue.
