Addresses and Fixes #23

This pull request introduces significant improvements to the project's development workflow, code quality enforcement, and benchmark analysis tooling. The key changes include adding comprehensive CI workflows for linting and testing on Ascend 910B hardware, automating test result reporting, enforcing consistent code style with pre-commit hooks and configuration, and refactoring benchmark analysis scripts for clarity and maintainability.

CI/CD and Test Automation:

• Added a new GitHub Actions workflow (.github/workflows/build-and-test.yml) for linting, style checks, and running unit tests on Ascend 910B hardware, including artifact uploads for debugging and test results.
• Introduced a test result reporting workflow (.github/workflows/report-test-results.yml) that automatically publishes JUnit test reports from CI runs, improving visibility into test outcomes.

Code Quality and Style Enforcement:

• Established a pre-commit configuration (.pre-commit-config.yaml) integrating tools such as isort, ruff, codespell, clang-format, and mypy, ensuring consistent code formatting, linting, type checking, and license header validation.
• Added an isort configuration file (.isort.cfg) to enforce import order and grouping according to the "black" profile and project conventions.
• Both are from upstream.

Benchmark Analysis Refactoring:

• Refactored benchmark/v1/rag/analysis.py for improved readability, consistent code style, and better error handling; added SPDX license headers and reorganized imports.
• Improved import organization and added SPDX license headers to benchmark/v1/rag/rag.py for compliance and clarity.
  Documentation:
• Fixed minor spelling errors in README.md for improved clarity.
