chore(tooling): Improve CI pipeline and expand pre-commit hooks

Expands the pre-commit configuration with a wider range of hooks to enforce file quality, validation, security, and Git safety checks.

The CI pipeline is updated to:
- Correct the `golangci-lint` format command to `fmt`.
- Enable CGO for test execution to support the race detector.
- Improve the robustness of test report parsing scripts.

Additionally, this commit includes minor stylistic and formatting cleanups across various project files.
