chore: update configuration files and improve linting for Windows

- Added `go1.24.0.linux-amd64.tar.gz` to `.gitignore`.
- Removed unnecessary newline in `.mergify.yml`.
- Updated `codecov.yml` to correct indentation for ignored files.
- Enhanced `Makefile` to support linting on Windows.
- Adjusted `.github/dependabot.yml` for proper indentation.
- Fixed string quotes in `.github/workflows/checks.yml`.
- Modified `pkg/container/util_windows.go` to ignore unused parameter.
- Updated error handling in `pkg/lookpath/lp_windows.go`.
- Refactored `pkg/runner/step_action_remote.go` to improve URL handling.
- Updated `pkg/runner/hashfiles/index.js` with significant changes for better performance and structure.
