feat: import thinking blocks from JSONL during CLI session import

- Include thinking blocks in single-pass JSONL parse (correct insertion
  order: thinking id < text id → displays before text via ORDER BY id ASC)
- Fix tool type: use 'tool' instead of 'tool_use' so getMsgsLite hides
  content and frontend skips tool rows correctly
- Backward tool-count scan already skips thinking rows (line 8128)
