fix: address Cubic round-2 P2 issues

- target-token-truncation: eliminate redundant SDK messages fetch by
  extracting tool results from already-fetched toolPartsByKey map
- recover-thinking-block-order: wrap SDK message fetches in try/catch
  so recovery continues gracefully on API errors
- thinking-strip: guard against missing part.id before calling
  deletePart to prevent invalid HTTP requests
