Add exponential backoff retry logic for vector store file operations (fixes #35)

   Implements retry mechanism with exponential backoff to handle eventual consistency
   issues when the OpenAI API returns 'No file found' errors immediately after file
   creation in vector stores.

   Changes:
   - Add resourceOpenAIVectorStoreFileReadWithRetry wrapper with exponential backoff
   - Retry up to 5 times with delays: 1s, 2s, 4s, 8s, 16s (total ~31s max)
   - Case-insensitive error detection for 'not found' and 'no file found' errors
   - Guard against invalid maxRetries configuration (must be >= 1)
   - Enhanced logging with tflog for debugging retry attempts

   Testing:
   - Comprehensive unit tests for retry behavior and edge cases
   - Acceptance test infrastructure with secure GitHub Actions workflow
   - Test data files for file upload validation
   - Made OPENAI_ORGANIZATION_ID optional (supports personal accounts)

   All tests pass with proper timing validation.
