v0.2.0
Per-task steps: a flat, ordered list on the task page with a shared notes and steps scroll region, step cursor, and modifier-protected add, toggle, rename, and delete verbs.
Headless commands:
herdr-tasks steps <task-id> add <text>creates a step.herdr-tasks steps <task-id> toggle <step-short-id>flips a step by unambiguous ID prefix.herdr-tasks list <task-id>prints each step with its state and short ID.
Step progress never changes the task's human status.
