feat: replace actions/checkout with manual git clone for Gitea compatibility

BREAKING CHANGE: Replace GitHub Actions checkout with explicit git clone

- Remove unreliable actions/checkout@v4 from all workflows
- Add manual git clone with HTTPS URL for deterministic behavior
- Explicit working directory control with 'cd repo' in each step
- Add debug verification steps to confirm repository context
- Fix npm install failures by ensuring correct working directory
- Update all 7 workflows: ci.yml, audit.yml, fix.yml, test.yml, security-scanning.yml, cli-level1-tests.yml, ci-cd.yml
- Use HTTPS clone URL for compatibility with Gitea runners
- Add 'rm -rf repo' to ensure clean clone each run

This resolves the issue where workflows were executing in hostexecutor directory
instead of repository workspace, causing npm install failures.
