Resilient LLM runner: model fallback chain, provider-death blacklist, cooldown, ANSI-repair

- llm.py: single retry/fallback/cooldown authority used by analyze/verify/pipeline
- provider [404] blacklists model + switches; rate limit escalates then cooldown
- unparsable model output (bad JSON/ANSI noise) skips to next model
- verify.py: DS_VERIFY_TIMEOUT, true rate-limit handling, honest FAILED reporting
- pipeline_all.py: honors model, reports verify status accurately
- aggregate.py: skip epNNNN_corrected.json strays (was duplicating ep 304)
- gitignore data outputs; drop stray analysis/analyst/analysts dirs
