fix: lighter nonce retry with fresh query + exclude tests from tsc build

- Lighter ChangePubKey: retry up to 3 times with fresh /nextNonce query
  between attempts (was: single nonce+1 retry with stale nonce)
- tsconfig.json: exclude src/__tests__ from build compilation to prevent
  vitest type errors in strict environments
- Fix flaky test: match "Unknown" instead of "Unknown symbol" for
  getAssetIndex error message
