- Fix PP calculation: use per-slot n_prompt_tokens during prefill state
instead of global llamacpp:prompt_tokens_total from /metrics
- Add isPrefilling flag and prefill tracking state (slotId, capturedTokens, startAt)
- Add dedicated formatters: formatPps, formatTps, formatAvg, pad4
- Replace formatRate suffixes with raw number formatters
- Display: PP | TPS | AVG with fixed-width 4-char padding
- Slot polling every 2s with model query parameter
- Debug logging to /tmp/oc-ls-stats-debug.log
- Add .npmignore, TUIPLUGIN.md, test-debug-log.jsonl
- Update AGENTS.md with slot state phases, PP calculation docs
