refactor: extract hardcoded constants to constants file

- Create autoDebug/constants.ts with retry configuration constants
- Replace hardcoded values in client.ts with imported constants
- Use camelCase naming convention for ESLint compliance
- Address reviewer feedback for better maintainability

Constants extracted:
- maxAttempts: 5
- initialDelayMs: 1000
- maxDelayMs: 10000
- backoffMultiplier: 2
