import: address review — pi branch-safe model, copilot streaming scan
Commit

- pi: extract the model over the [0,end) prefix (the same buffer token usage uses) instead of the [start,end) slice. Pi's branch-aware ExtractModel walks parentId back to the root, so the slice must keep the file's beginning; truncating only the end preserves those chains while still bounding the turn. Fixes wrong/empty per-turn model on branched sessions and when a turn's own assistant message omits the model. Adds a regression test.
- copilot: scan events.jsonl line-by-line and stop at the first session.start instead of reading the whole file and allocating via splitRawLines.
