fix: resolve all 15 lint errors failing CI

- Remove unused imports: buildCorrectionMessage, formatRetry, ToolPolicy,
  StoredMessage, stat, extname, estimateMessageTokens, estimateTokens
- Remove unnecessary type assertion in critic.ts
- Prefix unused var _MAX_SUMMARY_TOKENS in memory.ts
- Remove unused loop variable 'i' in memory.ts
- Fix eslint-disable-next-line placement for no-control-regex in logo.ts
