feat: Add retry mechanism with configurable attempts, wait time, and timeout

New input parameters:
- max-attempts (default: 1) - Maximum number of build attempts
- retry-wait-seconds (default: 0) - Delay between retry attempts
- timeout-minutes (default: 0) - Timeout per attempt (0 = no timeout)

Implementation:
- Wraps build execution in retry loop with comprehensive logging
- Adds timeout support per attempt using Promise.race()
- Fully backward compatible (default values maintain current behavior)
- Adds 2 test cases
