[feature] Infinite loop flow control

[ivicac]

Remaining item from #1057 (flow controls / task dispatchers): infinite loop is not done.

Current state:

• The loop task dispatcher has a loopForever parameter (documented in docs/content/docs/reference/flow-controls/loop_v1.mdx) and a companion loopBreak dispatcher, but the infinite-loop checklist item from [feature] Flow controls/Task dispatchers #1057 is not considered complete by this.

Scope: implement proper infinite loop flow control support (and document it in docs/content/docs/reference/flow-controls/).
