Animus_Sprint_Loops

Structured five-phase workflow (Research → Plan → Build → Test → Loop) for long-horizon coding tasks. Use when the user runs /sprint-loop, asks to start a sprint, continue a sprint loop, run an iteration, work in numbered sprints, or invokes phrases like "sprint loop", "start a sprint", "continue the loop", or "next sprint". Also use when a project root contains a `sprints/` directory and the user asks to resume work.

Structured five-phase workflow (Research → Plan → Build → Test → Loop) for long-horizon coding tasks. Trigger when the user mentions sprint loops, starting a sprint, continuing a sprint, or when the project root contains a `sprints/` directory.
