search-with-proof: startup environment and data files, dead-end dedupe, task_spend continues

Browse Source 
Demos may set a bounded environment (loader variables denied) and up to 8 small
data files under .demo/; the reason step sees conclusions and may not re-propose
them; a task spend limit concludes its intent, not the search; finish wins over
stray tool calls.
