Auto-detecting tokenId from memory/lp-positions.jsonl lacks robustness for empty/malformed files

- scripts/reposition.ts:215-223
If the file exists but is empty or the last line is malformed JSON, JSON.parse will throw and the process will exit with an unhelpful stack instead of a clear message. The earlier helpful error only covers the ‘file not found’ case.
Recommendation
Add checks for: (a) lines.length === 0, (b) try/catch JSON.parse with a user-friendly error, (c) validate that tokenId is a numeric string before using BigInt. Exit with a clear message.
