- scripts/ollama_usage_poll.py: per-minute cron sample into db/ollama_usage.sqlite,
write-on-change; meta table records every poll so a data gap can be told apart
from a failed or missed poll
- scripts/ollama_usage_report.py: delta report keyed on per-model request_count
(limits.*.usage has 0.1 % resolution, short-interval deltas are noise)
